Application limit for ES indexed field length

See merge request gitlab-org/gitlab!24345

There is an edge case when the parent `execute` fails and returns a user
with errors. This should be excluded from audit event logging.

When user is the sole owner of the group no explicit delete
options are enabled, the method is expected to return the
attempted delete user with error messages attached.

The test is to ensure we honour this interface and does not
cause unexpected failures from the callers.

Add version badge for Service Desk feature

Using the plan_limit table we can down store a limit for the maximum
size of any fields being indexed in Elasticsearch. This is for
https://gitlab.com/gitlab-org/gitlab/issues/201826 . Any strings above
the length limit will be truncated down to the limit.

We default to 0 which means unlimited so this has no affect for
self-managed customers. On GitLab.com we will likely want to set this to
around 20k as a sensible upper limit on what we should store.

Add test to ensure the return interface is honoured.

This method is called to record audit event for entities
other than `User`. There is more refactor effort required
to rectify those usages.

Integration test is also added to extend coverage for both soft
delete (delete user, not contributions) and hard delete (delete
user only).
