Beta - May 31st Release

Improvements: :

Front End:

• Only allow unit owners to invite new users to cases (#798)
• filter out case field values with a sort key of 9999
• including "Generic" sub-cat case field vals in all cat types
• Prompt instead of radio button if only one role is available for selection

MEFE API - Invitations:

• Improve how we process invitation of users to units. Retry handling for API requests and caching (#807)
• using a combination of request id and type for uniqueness

Bug Fixes:

• non-bounce ses notification payloads- error avoided.
• Automatic selection of the user's current role is now working as intended.
• Always include the user's own role, even if the settings tries to hide it (avoids unwanted edge cases).
• Detection of the whether a role has a default assignee before requiring invitation is now based on role information from Mongo and not BZ.
