Hi @tillrohrmann I added a unit test
`FsCheckpointStorageTest#testResolveCheckpointStorageLocation()` to guard the
changes. But I still use one `mock` for creating two different file systems(one
for checkpoint, another for savepoint), because without mock I can only create
a LocalFileSystem in the test. Could you please have a look again?---
