As an employer I would like to bulk upload employee data

Related to #507

@EStriegel Though marked for milestone 1 by me, We can't afford to implement this in milestone 1. Not having this feature essentially drives out several employers from using this application. There is no way I would see employers using this online application if they have more than 20-30-100 employers. It would be much easier to send in a paper application. However need specs for the upload schema and should be

Acceptance Criteria

[ ] Need upload schema from DOL
[ ] UI needs to implement Excel upload with data tables
[ ] API needs to support a method that accepts a collection of Employee information to upload and save to the database (implement security, validation prior to save, be cognizant of upload size & performance limitations.

NOTE: Remove any accessibility criteria that don't apply to this user story. For the full list of accessibility requirements, see issue #198, Fully Accessible Experience.

Functionality

[ ] functionality criteria 1
[ ] functionality criteria 2
[ ] etc.

Accessibility

NOTE: Remove any accessibility criteria that don't apply to this user story. For the full list of accessibility requirements, see issue #198, Fully Accessible Experience.

Keyboard Accessibility

[ ] An interactive element or function can be accessed or activated by keyboard
[ ] keyboard "trap" not found
[ ] if non-standard keyboard commands are needed and they are documented
[ ] TITLE provides information and equivalent information is found through text or visual context
[ ] The visual focus can be determined at all times.
[ ] focus always appears on the element it is programmatically on.
[ ] if focus remains in the modal dialog box until the box is closed.
[ ] if focus moves to revealed content OR a description of the content change is provided.
[ ] the tab order is logical

Web: Forms

Web forms include controls (checkboxes, radio buttons etc.), and editable content (text input, select options etc.).

[ ] all form fields and their instructions and cues have HTML (‘Label for’ and ‘ID’ are used or TITLE is descriptive) or ARIA for association.
[ ] All 'Label for' and 'ID' are valid code pairs.
[ ] All form instructions that are provided by mouse over are available onscreen.
[ ] All ARIA form fields have a NAME property that contains all of the instructions.
[ ] All ARIA form fields have correct Role, State, and Value properties.
[ ] All form controls identify their purpose. (Check if there are multiple form controls with the same visual label).

Web: Links and User Controls

Links and/or user controls must have meaningful names that describe the unique destination, function, and/or purpose of the control for assistive technology.

[ ] All links have a unique and meaningful description.
[ ] All scripted elements have a unique and meaningful description.

Web: Images

Web images include interactive images (links, buttons etc.), static images, charts, diagrams, text rendered as an image, etc.

[ ] All images have an ALT, TITLE, or ARIA attribute.
[ ] All meaningful images with ALT have an equivalent text description.
[ ] All decorative images with ALT have ALT="".
[ ] All images that contain text with ALT have the same text in the ALT attribute.
[ ] CAPTCHA images describe their purpose. (DNA, after the captcha is removed)
[ ] All components that have multiple statuses provide their current status

Web: Image Maps (if no image map, then DNA)

An image map is a single image that has designated regions or "hotspots" that contain links.Server-side image maps may not be used. Client-side image-maps must be used instead

[ ] All image maps are client side

Color and Contrast

Color dependence is using color as the sole means to convey information. There must be contrasting colors/shades at a ratio of 4.5:1 for discerning between background and foreground content.

[ ] if color is used but is not the only method to provide information.
[ ] if the contrast ratio is 4.5:1 or greater when comparing all background and foreground colors. Page titles Programmatically identify Page Titles.
[ ] There is a meaningful page title in plain language.

Time Outs

Messages and/or instructions to the user requesting their response within a given time are typically associated with sites that require a secure login. This includes both server time outs and client side security time outs. If a time out is about to occur, an alert must be posted for at least 20 seconds and the user must have the option to request more time. The alert (often a pop up window) and option to request more time must be keyboard accessible.

[ ] The application provides notification before timing out.
[ ] The application's time out notification is displayed for at least 20 seconds before timing out.
[ ] The application provides user an option to request more time before timing out.

Web: Language

A default language must be programmatically identified for each page and for passages that use a language other than the default.

[ ] if the correct default language for the page is programmatically set.
[ ] if there is not a passage in a language that differs from the default language of the page.

Web: Section Headings

Headings must be programmatically identified and must match the visual outline level.

[ ] All visually apparent headings are programmatically identified with an . ( levels do not need to be correct.)
[ ] Programmatic levels on all visually apparent headings match the visual structure.

Web: Data Tables (If no table, then DNA)

Data tables are those tables where the information in a cell requires a row or column header to adequately describe the cell's contents.

[ ] HTML data tables' row and/or column headers are correctly identified programmatically.
[ ] if there are data tables but none of them are images.
[ ] if all HTML complex data tables' data cells are associated with their headers programmatically.
[ ] if there are complex data tables but none of them are images

Web: Style sheet Dependence

style sheets are a means to provide visual formatting information to complement a web page's content.

[ ] The order of the content did not change OR if the order of the content changed but is still logical.
[ ] All relevant content and information from all meaningful images is available.
[ ] All content does not overlap and stays legible.
[ ] If no confusing elements are revealed on the page.

Web: Frames

Frames are a means of separating out sections of a web page into different navigable regions

[ ] if all frames' Title or Name is descriptive.

Web: Repetitive Content and Links

[ ] There is a method to skip repetitive content.
[ ] There is a target for all skip links.
[ ] All skip functions work properly
[ ] If the relative order of the repeated components is the same as other pages.

Web: Required Plug-ins (if no plug-In, then DNA)

[ ] if on a public site, links to download all required plug-ins are provided.
[ ] All plug-ins required to view content are compliant.

QASP requirements

These requirements are taken from the Quality Assurance Surveillance Plan

[ ] at least 90% code coverage
[ ] no linting errors
[ ] deploys successfully
meets security requirements
- [ ] static scan
- [ ] OWASP ZAP
- [ ] false positives documented
