* Allow automatic rebuilding of CRLs
When enabled, periodic rebuilding of CRLs will improve PKI mounts in two
way:
1. Reduced load during periods of high (new) revocations, as the CRL
isn't rebuilt after each revocation but instead on a fixed schedule.
2. Ensuring the CRL is never stale as long as the cluster remains up,
by checking for next CRL expiry and regenerating CRLs before that
happens. This may increase cluster load when operators have large
CRLs that they'd prefer to let go stale, rather than regenerating
fresh copies.
In particular, we set a grace period before expiration of CRLs where,
when the periodic function triggers (about once a minute), we check
upcoming CRL expirations and check if we need to rebuild the CRLs.

* Allow modification of rollback period for testing
When testing backends that use the periodic func, and specifically,
testing the behavior of that periodic func, waiting for the usual 1m
interval can lead to excessively long test execution. By switching to a
shorter period--strictly for testing--we can make these tests execute
faster.
