Update: Various Elections API changes, Part 2

[jbriones1]

Updates

• Updated the metadata for the elections endpoints so that our docs are accurate
• Singularized the election endpoints and moved the election endpoints to their own root path
  • /elections -> /election
  • /elections/registration/ -> /registration
  • /elections/nominee_info/ -> /nominee
  • This enforces a pattern where each table has its own set of operations. We can always make endpoints that do more complicated things, which compose multiple operations in a single call.
• Changed GET /elections/list -> GET /election
  • Removed the constraint that elections can't be named "list"
• Updated all PATCH endpoints to the following pattern:
  • The URL params are used to target a specific database entry
  • The body holds the values that will be used to update the entry
  • The entry's fields will only be updated if there is an explicit value set in the body (so a body.speech that's NULL will set it to NULL in the database, but if body.speech doesn't exist then the entry's value will not change)
• Updated all the POST endpoints to use the body as the entry's values
• DELETE endpoints target a single entry in the database using the URL parameters
• Made some endpoints require you to be an admin
• All current elections unit tests should all pass
• Made enums for officer positions and election statuses
• available_positions will automatically be converted to a str when saved to the database and to a list[str] when used in the Python code
• Moved nominee-application-related things to the registrations folder
• Moved nominee-info-related things to the nominees folder

Todo (Part 3)

• DELETE /nominee/{election_name}/{computing_id}/{position: to delete nominees
• POST /nominee: to create nominees (PATCH does this, but semantically that's kind of weird)
• Add unit tests for all the newer endpoints
• Break up unit tests for easier debugging
• Remove some constant strings that are floating around and convert them to enums if possible
