Review Comment:
Should also be moved to HRegionFileSystem.hasReferences(), like other
methods did?
Additional question: Is it guaranteed that we don't have more than one SFT
instance for the same store at any point in time? Because the file based SFT
impl relies on the fact it's the single instance manipulating its meta files.
If we have multiple instances of SFT for the same store, it could lead to
inconsistencies, where one of the instances update the meta file, than the
others would be looking at an outdated state of the meta files.
