* Load credentials and pass to ObjectStorage plugins
Update NewObjectBackupStore to take a CredentialsGetter which can be
used to get the credentials for a BackupStorageLocation if it has been
configured with a Credential. If the BSL has a credential, use that
SecretKeySelector to fetch the secret, write the contents to a temp file
and then pass that file through to the plugin via the config map using
the key `credentialsFile`. This relies on the plugin being able to use
this new config field.
This does not yet handle VolumeSnapshotLocations or ResticRepositories.

Refactor plugin management:
- support multiple plugins per executable
- support restarting a plugin process in the event it terminates
- simplify plugin lifecycle management by using separate managers for
each scope (server vs backup vs restore)
