crimson/osd: handle MOSDScrub2

MOSDScrub2 is sent from mgr for serving "ceph pg
{scrub|deep-scrub|repair}' commands when it's talking to a mimic and newer OSD.

ceph task checks if all pgs are scrubbed by looking at the `last_scrub_stamp` fields
in the `ceph pg dump` output. and it request the not-yet-scrubbed pgs a
deep scrub to ensure they are scrub before timeout.

in this change, crimson handles MOSDScrub2 by starting a remote peering
request, and the underlying peering_state will notify the corresponding
PG to start scrub. to get the test pass, a minimal implmentation is
added to update the scrub timestamp to `now` upon request of
peering_state.

we will need to add the correct scrubbing support later. but this is
enough for passing the thrasher test and for preparing for more tests
which uses the "ceph" task.

cephadm: add unwrap_ipv6 helper method

When we pass in a mon-ip that is ipv6 we want it wrapped, this is so it
can be properly inserted into the mon_addrv address.
But there are times we need to unwrap it to test it's a valid ipv6
address.

This patch adds a helper method `unwrap_ipv6` which takes a string and
returns it either unwrapped or as it is, so it's harmless to other types
of ips.

This allows us to check a wrapped ipv6 base_ip with the networks on the
host.

mgr/cephadm: fix call to cephadm for daemon restarts etc

The call currently passes the daemon_type as the first
parameter - but the function expects the hostname. This
results in failures when attempting daemon restarts through the ceph orch daemon <action> <daemon_id>
command.

osd: don't write transaction when inc crc failed

80da5f9a987c6a48b93f25228fdac85890013520 exposed a flaw in how
handle_osd_map falls back to a full osdmap if the crc of an incremental
failed.

If the first message in a map message had a crc error, then the

dereference in _committed_osd_maps.
