Add namespace support to GitLab Secrets Manager
What does this MR do?
Add namespace support to GitLab Secrets Manager
While secret path is correctly constructed to allow
<namespace_path>/<engine_path>, authentication occurs via a different
path, <namespace_path>/auth/<auth_path>/<login_path>; while commonly
login_path is just "login", notably namespace and auth mount paths are
on different sides of the literal string "auth/". This means the current
construction (only giving control over <auth_path>) does not work for
injecting namespaces from GitLab Secrets Manager into Runner's inline
authentication.
We resolve this by using a single fixed (full, minus the /v1/ prefix)
authentication path, while retaining two-way compatibility with
older/newer GitLab Rails versions.
