filestorage is only used for testing at the moment.

environs/localstorage takes over from environs/sshstorage, reusing the
storage directory. However, there is no overlap in use;
environs/sshstorage is only used to write the tools and bootstrap state
file. *If* there's a failure bootstrapping, the bootstrap storage may
also be used to remove the state file.

Since there's no overlap, there's no need to share the locking. I did
just realise that I totally broke the manual bootstrap code though, when
I changed sshstorage's directory structure. I'll have to revisit that
before merging.

This is only for testing, but I will fix it anyway. I think localstorage
ought to be renamed httpstorage, and have the backend contain one of
these.

They're pointing to the same location, but they're never used
concurrently.
