Setup Unity-Test UI/portal, and get domain approved by URS

[galenatjpl]

As a necessary prerequisite to getting https://github.com/unity-sds/unity-project-management/issues/71 done, we want to make sure some basic domain name support is in place on the Unity-Test account. Specifically, the Unity-Test account should have a portal, that is accessed by means of https://unity-sds.jpl.nasa.gov/.

For this to happen, two main steps are required:

1. Stand up a Shared Services “main” public API Gateway endpoint on our MCP account, that points to a skeleton Unity website in Unity-Test, made to NASA templates/standards This site is most likely, https://58nbcawrvb.execute-api.us-west-2.amazonaws.com/test/portal/index.html, but @mike-gangl will confirm.

2. Reach out to URS, and get the above URL/domain approved for Unity-Test

Acceptance Criteria:

• [ ] Portal is deployed (with API Gateway) on Unity-Test
• [ ] Portal has UI that's NASA compliant
• [ ] URS has reviewed the portal/endpoint, and approved of the domain
• [ ] The necessary AWS glue is configured so that the portal is using the domain.
• [ ] Confirm that accessing https://unity-sds.jpl.nasa.gov/ takes a User to the portal

UPDATE: @mike-gangl requested a URS review of our portal to get our unity-sds.jpl.nasa.gov domain name
