MOSDPGCreated messages are used to prune the creating_pgs_by_osd_epoch
and creating_pgs, by updating created_pools. as once a pool is created
we will not send MOSDPGCreate to its acting_primary OSD anymore.

add an option named "osd_created_report_interval" to specify the
interval to check and send the "pg_created" mesages to mon
because pg could update its state when it is still in the pg_stat_queue,
for example, to change its state to PG_STATE_CLEAN, we cannot tell if we
have sent a "pg-created" message for it or not without introducing a new
member variable in PG.

add a new message type MPGCreated. osd is supposed to send this message
to monitor to inform that any pg(s) is created and activated.

OSDMonitor will handle the pg-create subscriptions after luminous.
1. scan new pools to get the pgs to be created
2. send pg creates using the collected pgs
3. trim the creating_pgs using the "created!" messages from OSD.
please note that we need to wait for the OSDMonitor::mapping to be fully
populated, so we cannot scan the incrementa map for creating pgs until
it is applied and accepted by other monitors.

we will access the mon->session_map for sending the osd-pg-creates
messages when finishing osdmapping in OSDMonitor, this could happen in
another thread without the protection of Monitor::lock, or in the same
thread already guarded by Monitor::lock. so instead of changing
Monitor::lock to a recursive lock, a new lock is introduced to protect
session_map.

otherwise subcriptions on peons won't get the creating_pgs notification
mapping updated. we want to send the notification from peons also. and
the notifications should be updated with the updated pg mapping.

as pg_creatings needs mapping to get the acting_primary osd of the
creating pg, so we can send the pg-create message to it if it subscribes
to this information, mapping should always be available now.

osd will send beacon message to monitor periodically to inform it that
"i am still alive!", previously, monitor use the pg-stats to check the
status of OSD, but since osd will only send pg stat to mgr after
luminous, we use a dedicated msg for this purpose.

this change updates the comment for 7fb3804fb, 97462a3 and e807770,
to reflect the reason why we need to fix latest_full in current code.
as the fix is not a workaround for cuttlefish anymore, it resolves the
issue where
0. mon.c has a latest_full of 5
1. mon.c is shutdown and out of sync with the quorum
2. mon.c starts sync
3. mon.c now has osdmap[31..50], and the latest_full is still 5.

Make Device::last_poll_dev `unsigned` - it could overlap and should not
be negative.
Also, add missing initialization.

Setting RDMA_DEBUG to 1, will enable debug prints for every ibv_*
function called.
This makes it easier to debug RDMA issues.

Encapsulate all connection establishment stuff in a new class -
RDMAConnMgr and make it a friend class of RDMAConnectedSocketImpl.
This class will be inherited for every type of connection establishment
- Currently only TCP is supported, very soon CM will be added too.
RDMAServerConnImpl which only handle connection establishment became an
abstract class and RDMAServerConnTCP is inherting it for connections of
type TCP.
Some of the code was left in its original file and place, and therefore
it looks misplaced. This was done to make it easier to review and rebase.
Once it is accepted a cleanup patch will be sent to move the code into
the right place.
