The `regenerate-schema` script attempts to find the merge base between
the source and branch SHA to determine the right `db/structure.sql` to
apply the migrations in the merge request. However, to get the merge
base, we need the target SHA and the history between the source and
target SHAs. Instead of downloading it via a curl request, we fetch the
target branch and check out the `db/structure.sql` from there.

Quarantine pull mirroring spec while we investigate the issue

Decouple partial clone config

See merge request gitlab-org/gitlab!30354

Previously partial clone configs is coupled with receive_max_input_size
check. This make sense when you think of partial clone as a replacement
for Git LFS but in truth, the 2 features are separated and should not be
 decoupled.

In self-managing instances, `receive_max_input_size` could be set to 0
while users could still wish to have partial clone feature enabled.

Switch Gitlab::JSON to JSON for helm3_client

Closes #216365

See merge request gitlab-org/gitlab!30944

If the sidebar Ajax request finishes after loading the Ajax request for
a specific issue, it will clear the assignee, leading to the test
failure. We work around this issue by waiting for the initial request to
be done.
