Commit Message

CP-49135: speed up UUID generation (#6018)

2 optimizations here:
* open /dev/urandom just once, speeds up session uuid/ref creation by
~3.8x
* use a PRNG for non-secret UUIDs. We cannot use these for sessions
(those UUIDs/opaquerefs are effectively the authentication tokens), or
Pool secrets, but we can use it for everything else.

The latter is not yet enabled by default, needs more testing/auditing on
whether we have any other secret opaquerefs/UUIDs in the codebase, but
the 1st one is enabled by default (we still use `/dev/urandom` for
generating the UUIDs, we just don't keep closing and reopening it).
