[Enhancement] Improve FRED Search

[deeleeramone]

1. Why?:

   • The full-text search returns too many results and we can make it a little more targeted.

2. What?:

   • Implements a post-request regex in transform_data that filters rows for the query term(s).
   • Adds the order_by enums with asc desc for the sort order.
   • Reconfigures is_release to be search_type with choices: ["full_text", "series_id", "release"]
   • Adds query validators to help prevent bad input and communicate the error.
   • Applies "limit" post-request as opposed to part of the request.
     • Allows for the post-request filtering to narrow the field.

3. Impact:

   • Does not impact any Pro implementations.
   • is_release is now a choice ("release") in search_type.
   • Enhanced search function with higher quality results.
   • Improved error handling and validation.
   • Default state is:
     • No user input: Returns the list of all Releases ~ 400 results.
     • No parameters other than "query": Full text search, in descending order by "observation_end".
     • No parameters other than "release_id": Returns the list of all series within that specific release.
     • "release_id" & "query": Applies the regex post-request filter.
     • No parameters other than "series_id" (needs to have geo data associated with it - "NYICLAIMS"): Returns the series group metadata.
   • No parameters other than "query" and "search_type" set to "series_id":
     • Filters for series IDs specifically

4. Testing Done:

   • Updates integration and unit tests.
   • Various combinations of all the params.
