[ML] Use feature reset API in ML REST test cleanup (#71746)
Browse files Browse the repository at this point in the history 
Now that we have a feature reset API, we should use
this for cleaning up in between tests instead of running
lots of bespoke cleanup code.

During testing of this change we found we need to
delete custom cluster state as part of the reset process,
so this PR also implements that.

Additionally we no longer assign persistent tasks
during feature reset.

Backport of #71552
