[Bug 1555137] [NEW] Transition from UUID/PKI to Fernet without dumping all tokens

 

Public bug reported:

To minimize downtime, the conversion from persisted to ephemeral tokens
should happen in two steps.  The first migrates tokens over to the
Fernet format, but will fall back to persisted store if the requested
token is not in Fernet format.  The second removes persistence.
