Due to this failure
https://gitlab.com/gitlab-org/gitlab/-/issues/212185
I've changed the way some of the effected tests add
members to groups or projects so that they use the
API which is faster and avoids the error above
without impacting the integrity of the test.

Refactor JSON reader/writer for import/export

See merge request gitlab-org/gitlab!27679

- adds `allowed_path` to strong validate `LegacyReader`
  and `LegacyWriter`
- does not change any of todays behaviour for data serialization
- makes the interface for reader and writer to accept
  `importable/exportable_path` that will be used by `ndjson`
  to store data in separate files
- moves consuming of attributes outside of the relation tree restorer
  to ease the way how we process them
- splits specs for `LegacyReader::User/File` and introduces
  shared example for that: this is also the majority of changes
  introduced by this MR in order to move them
- slightly code-formats and re-organises group and project
  import/export

Use prefix search instead of ngrams for sha fields

See merge request gitlab-org/gitlab!27597

Currently, SHAs are indexed using ngrams from 5 to 40 characters. This
means that each SHA is split into 35 separate terms taking up a lot of
storage. SHAs are quite unique from 4-5 characters on, so a simple
prefix search will be sufficiently fast and as effective as ngrams with
term matching. This change replaces current sha fields analyzers with
prefix search.
