Notifications Page

[jacksonjacobs1]

Description

A robust mechanism for providing system notifications to the user should be added to QA

Implementation notes

• QA has a database table called Notification which is expected to be updated both by flask endpoints and ray tasks.
  
• proj_id and image_id are nullable foreign keys. mesage_type is used to meaningfully differentiate notifications from e.g., ray cluster vs. flask server.
• The slickgrid should support infinite scrolling while also lazily loading data off of the server. https://ghiscoding.github.io/slickgrid-react/#/example40
• The notifications page should use a polling approach to update.

Acceptance criteria

• Clicking the bell icon on the right-hand side of the navbar should open the notifications page.
• The notifications page should display an infinitely scrollable slickgrid.
• The user can mark notifications as read. (low priority - this may not be useful)
• The server should be able to add new items to the notifications table.
