Detect if keymgr made changes

Browse Source 
If so we also want to tickle the apex because DNSKEY/CDNSKEY/CDS
RRsets may need to be re-signed.

Note that this may be overzealous, because if state transitions
happen just because of timing events (RUMOURED -> OMNIPRESENT,
UNRETENTIVE -> HIDDEN) this would have to cause changes in the
zone DNSSEC records.
