Implement email notifications in Scholar 3

[jamesvanmil]

Need to review Scholar 2 email functionality and current Sufia notification/email decide what's important to port.

Includes:

• New user emails
• Change manager notification emails

[scherztc]

Email on creation or first login. Email on editorship/proxy role. Email on embargo.

Look into User Notifcations.

possible tie in point:

app/controllers/concerns/sufia/dashboard_controller_behavior.rb

[lawhorkl]

we dont even need the change manager gem as from reading mailboxer's docs say: https://github.com/mailboxer/mailboxer

[lawhorkl]

test more on embargoes and proxy actions

[lawhorkl]

investigate dashboard behavior more about what does and does not get sent

send email to @ntallman about new email content in scholar 3

@report from dashboard testing:

Behavior on proxy batch create:

• Generates a notification for each work created and a separate one for when the work is transferred to the proxied owner.
• Location of batch create:

Behavior on non-proxy batch create:

• Generates a notification for each work created.
• Sends an email for each work created

Behavior on adding or removing a proxy:

• Generates a notifications when adding or removing a proxy. Does not cancel inverse actions.

Behavior on embargos:

• Having a hard time testing this

Behavior on creating or deleting collections:

• No notification is generated in the dashboard.

Behavior on adding or deleting works to/from collections:

• No notification is generated in the dashboard.

Behavior on transferring of ownership:

• On transferring of ownership of a work, a notification is generated in the dashboard.

Behavior on modifying a work's attached file and/or uploading/restoring revisions to files:

• Sends notification to dashboard and then sends out email.

We will probably need to wait for Shibboleth integration for the welcome email
