feat(Findings): Partitioned database tables (#45)

* feat(Findings): initial findings model

* fix(Findings): add view, serializers, migration for enums

* fix(Findings): incomplete jsonb_to_tsvector wrapper

will not run as written

* fix(Findings): use Severity and Status enums from prowler SDK

* tests(Findings): add failing view tests

* fix(Finding): add resource relationship

not returning correct data from serializer, missing links

* fix(FindingSerializer): get Scan & Resource relationships to show up

* fix(FindingFilter): add more filter fields

* fix(FindingFilter): filter on provider id

* fix(FindingSerializer): return Resource in relationship

not ResourceFindingMapping

* fix(FindingModel): update migration

* fix(FindingFilter): full text search on findings

* fix(Resources): include Findings in ResourceSerializer

* fix(FindingFilter): expand text search columns

* fix(DbUtils): docstring, not comment

* fix(BaseViews): remove TODO

comment not applicable right now

* fix(Fixtures): add more findings to fixture file

and change on_delete behavior for resource_finding_mapping

* fix(Resources): rename index to match others

* fix(Findings): update Findigns RLS to allow for full CRUD

eventually we'll let users enter a manual finding
which implies INSERT, UPDATE, DELETE

* fix(Findings): use TextChoices directly for Status enum

* fix(FindingSerializer): build a set instead of a list

* consistency in fixtures
