Remove support to pass backup bucket endpoint information through the credential file(s) #970
Description
How to categorize this issue?
/area backup robustness
/kind cleanup
What would you like to be added:
Remove support in passing backup bucket endpoint information through the credential file(s).
This applies to all providers that currently utilize --store-endpoint-override.
Why is this needed:
#952 introduced the --store-endpoint-override flag which can be used to override the endpoint at which the storage provider's bucket is hosted. This information was originally passed as a field in the credential file.
Since the credential file should not contain such information (#943), support for this should be removed in v0.42.0 release of etcd-backup-restore.
Support for this was kept till v0.42.0 to ensure backwards compatibility after the first release which includes #952, and provides enough time to consumers to adapt their credential files.
