If dnssec-policy is reconfigured and the key lifetime has changed,
update existing keys with the new lifetime and adjust the retire
and removed timing metadata accordingly.
If the key has no lifetime yet, just initialize the lifetime. It
may be that the retire/removed timing metadata has already been set.
Skip keys which goal is not set to omnipresent. These keys are already
in the progress of retiring, or still unused.
