Workaround to deal with old pickle files
Importing pickle for backwards compatibility
Typo
Replaced references to pickle with gzipped JSON
Use jsonpickle to store JSON-ifiable data in the file cache
Fix file closing issue.
Write gzipped json and catch and raise errors when reasing a pickle
Use a string key in the nagios cache

- Python's JSON fails to convert integer keys correctly
- id /= decode . encode
Return a boolean if the update stores new data
