Rename OUT_OF_KEYS -> OUT_OF_KEYS_TRANSIENT

More OUT_OF_KEYS errors are coming, and the old "OUT_OF_KEYS" is a
bucket for all transient errors. Rename the enum to better indicate
this.

Also rename OUT_OF_KEYS_REQUIRES_UPGRADE to
OUT_OF_KEYS_REQUIRES_SECURITY_PATCH. This better indicates that
system is potentially vulnerable (rather than simply running old code).
