This change is part of
https://gitlab.com/gitlab-org/gitlab/-/issues/212566 to move all Design
Management code to FOSS.

This MR moves:

- Models
- Factories
- Design repository-related code

The repository-related code has been included because the models and
model specs rely on design repositories to be working.

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.

Fix error when running update-tests-metadata in master

but we missed another instance of the same problem
