Tasks in this PR

• Add a 'JWT cache' concept inside the authenticator, preparing the way to encrypt the data.
• Add an authenticator class to pull together lots of tightly-bound functions
• Logoff should accept a bootstrap flag to make it symmetrical abandoned because we want to move to a context and away from bootstrap
• Logoff should remove the file using cache.clear rather than zapping the underlying file.
• Move some interfaces to an spi folder so we can avoid cyclic dependencies easier.
• The bearer token code in utils is the only thing which knows where bearer tokens are stored. (In the ~/.galasa/bearer-tokens folder)
• The cache is the only thing which manipulates bearer tokens
• Logout flushes all cache entries
• A JWT in the cache which has expired is treated as not existing at all, so a new one can be allocated.
• Linted the code a bit, and cleaned up some of the warnings.
• Each server has it's own jwt stored in the cache. Stored in a folder whose name is the uuencoded api server URL. So they are unique files.
• The files are encrypted before they are written to disk. Using the galasa token.
• The files are accessed using exclusive lock access. So one tool instance can't interfere with another.
