JWT files mode

• Adds a files mode to JWT, allowing to check ACLs only through a static-files-like interface.

Release 1.5.0

Additions in this release:

• Cache jitter: a jitter can now be set for the cache to add randomness to expirations.
• Backends retry: retries on checks may be set to handle sporadic failures.
• Test Docker image.
• Backends registration: backends may register which checks they'll perform.
• General cleanup.

Major kudos to @PierreF for bringing in most of the enhancements.
