Add GetObjectLockConfiguration satellite endpoint (object retention)

[amwolff]

Goal

This issue is to make meaningful progress on Object Lock implementation within core and edge services. Specifically, to support immutable backups in backup software products like Veeam.

What needs to be done? • Acceptance Criteria

Add the corresponding to GetObjectLockConfiguration endpoint on the satellite (the endpoint can be named differently) to respond with the following:

• the information whether the bucket is Object Lock-enabled
• bucket-wide retention settings are out of scope at the moment

Summary
