(cherry picked from commit 89692e099f)
If the client is sending replay requests, avoid sending embedded caps,
since the mds already has the client's caps from the reconnect.
This matches the behavior of the kernel client.
Fixes#4742.

The request forwarding infrastructure is there for client requests.
However, we (ab)use it for mon's sending MLog messages: LogClient sends an
MLog message to itself, and that is either handled locally (if leader) or
forwarded to the leader.
If that races with an election, we were forwarding an MLog from another mon
to the leader. This is not necessary; the original MLog sender will resend
the request on election_finish() to the latest leader.
The fix is to adjust forward_request_leader() to only forward messages from
a mon if that mon is itself.
This was reproduced while testing the fix for #4748.

This is somewhat annoying actually. Intuitively we want to
clear_primary_state when we leave primary, but when we restart
peering due to a change in prior set status, we can't afford
to forget most of our peering state. want_acting, on the
other hand, should never persist across peering attempts.
In fact, in the future, want_acting should be pulled into
the Primary state structure.

There are intervals during bootstrap(*) during which we are part of the
monmap, but our name (mon->name) does not match the monmap's. This means
that calling monmap->get_inst(mon->name) is not a safe way to get our own
entity_inst_t.
Instead, use messenger->get_myinst(). This includes our addr (obviously)
and an up-to-date entity_name_t, too: in bootstrap we adjust the messenger
name at the same time as mon->rank, based on the contents of the monmap.
monmap->get_inst(mon->rank) would work too.
* During mkfs, the monmap may have noname-foo instead of the name if it was
generated from the mon_host lines or dns or whatever by
MonMap::build_initial(). This was the case for #4811.

This patch fixes a bug in radosgw swift compatibility code,
that is, if a not-owner but authorized user access a non-existing
object in a container, he wiil receive unexpected error code,
to repeat this bug, do the following steps,
1 User1 creates a container, and grants the read/write permission to user2
curl -X PUT -i -k -H "X-Auth-Token: $user1_token" $url/$container
curl -X POST -i -k -H "X-Auth-Token: $user1_token" -H "X-Container-Read:
$user2" -H "X-Container-Write: $user2" $url/$container
2 User2 queries the object 'obj' in the newly created container
by using HEAD instruction, note the container currently is empty
curl -X HEAD -i -k -H "X-Auth-Token: $user2_token" $url/$container/obj
3 The response received by user2 is '401 Authorization Required',
rather than the expected '404 Not Found', the details are as follows,

If you use -a to start a remote daemon, assume the remote config is present
instead of pushing the local config. This makes more sense and simplifies
things.
Note that this means that -a in concert with -c foo means that foo must
also be present on the remote node in the same path. That, however, is a
use case that I don't particularly care about right now. :)

Once we're sure an object doesn't exist, we retry all the waiters in
order, and they return -ENOENT immediately. If there were a bunch of
BufferHeads waiting for data (rx state), they would be left behind
while the reads that triggered them were complete from the cache
user's perspective. These extra rx BufferHeads would pin the object in
the lru, so they wouldn't be removed by release_set(). This meant that
the assert during shutdown of the cache would be triggered.
To fix this, remove any BufferHeads in this state immediately when we
find out the object doesn't exist. Use the same condition as readx for
determining whether this is safe - if we got -ENOENT and all
BufferHeads for the object are clean or rx.

In general anybody participating in an election should be new enough to
lead thanks to the bootstrap process, but we've observed situations in
which a monitor is leader but gets so busy that it gets booted out
without noticing for a while, then processes the election messages
which were spawned, responds to them, and the other monitors kick those
up to a new election epoch. Then the old and behind monitor gets
elected as the new leader, which does bad things to our sync.
To deal with this, add the paxos first and last committed versions
to the MMonElection messages, and consider those values when deciding
whether to defer to a peer. Only defer to them if their newest value
is newer than our oldest, but also *do* defer to them if their oldest
value is newer than our newest even if we out-rank them otherwise.

We were looking at our own paxos_max_join_drift and using that to
calculate whether we were new enough to join without syncing, but
if those numbers don't match across monitors they might have trimmed. Use
the number they provide us as their first version and compare to that
as well.
