refactor(cache): rewrote/refactored cachedb functionality to use interface (#667)
Moved boltdb to a driver implementation for such interface
Added CreateCacheDatabaseDriver in controller
Fixed default directory creation (boltDB will only create the file, not the dir
Added coverage tests
Added example config for boltdb
Re-added caching on subpaths, rewrote CreateCacheDatabaseDriver
Fix tests
Made cacheDriver argument mandatory for NewImageStore, added more validation, added defaults
Moved cache interface to own file, removed useRelPaths from config
Got rid of cache config, refactored
Moved cache to own package and folder
Renamed + removed cache factory to backend, replaced CloudCache to RemoteCache
Moved storage constants back to storage package
moved cache interface and factory to storage package, changed remoteCache defaulting
