Jeff Mitchell 801e531364 Enhance transit backend:
* Remove raw endpoint from transit
* Add multi-key structure
* Add enable, disable, rewrap, and rotate functionality
* Upgrade functionality, and record creation time of keys in metadata. Add flag in config function to control the minimum decryption version, and enforce that in the decrypt function
* Unit tests for everything
