Add ability to override credentials for accessing base backup in S3

Browse Source 
Sometimes credentials with which the backup had been done are inactive
already, and ClickHouse will not be able to read the metadata file to
continue and fail.

Add a setting to allow ignoring credential from base_backup -
`use_same_s3_credentials_for_base_backup` (default to true).

And the same for RESTORE.
