[Sanity] Added test to check fernet token rotation is consistent
The test checks that /var/lib/keystone/fernet-keys/ directory at ctl*:
* has the same files and same number of files;
* all same files on different ctl* nodes have the same MD5 sum.
When fernet token rotation is not equal on all ctl* nodes and these files
are not consistent, the OpenStack API works unexpectedly and responds with
random 500 HTTP errors for random requests.
