[Bug]: ActionsSource fails with 412 when there is load on KV

[itaigilo]

What happened?

When KV store is experiencing loads, the ActionsSource mechanism doesn't retry the catalog.GetEntry() and catalog.GetRepository() calls. It results in failing the loading of pre-hooks, which result in a very confusing 412 errors (and not applying the actions, of course).

Steps to Reproduce:

1. Simulate a load on the KV store.
2. Run a process using actions.

Actual Result:

• Many 412 errors.

Expected behavior

Server should return 420 error in this case, so that the clients might be able to better handle this.
