AsyncConnection: Fix mark_down race condition
Previously, if caller want to mark_down one connection and caller is event
thread callback, it will block for the wakeup. Meanwhile, the expected event
thread which will signal the blocked thread may also want to mark_down
connection which is own by already blocked thread. So deadlock is happen.
As tradeoff, introduce lock to file_events which can avoid create/delete
file_event callback. So we don't need wait for callback again.
If binding on a IP-Address fails, delay and retry again.
This happens mainly on IPv6 deployments. Due to DAD (Duplicate Address Detection)
or SLAAC it can be that IPv6 is not yet available when the daemons start.
Monitor daemons try to bind on a static IPv6 address and that might not be available
yet and that causes the monitor not to start.

AsyncMessenger: Using EventCenter instead of poll for bind
Totally avoid extra thread in AsyncMessenger now. The bind socket will be
regarded as a normal socket and will dispatch a random Worker thread to
handle accept event.

AsyncMessenger: Bind async thread to special cpu core
Now, 2-4 async op thread can fully meet a OSD's network demand with SSD
backend. So we can bind limited thread to special cores, it can improve
async event loop performance because most of structure and method will
processed within thread.

The json-pretty format was modified for readability and now includes
additional newlines / spaces. Either switch to json to avoid dealing
with space changes or modify the expected output to include them.

common: restore format fallback semantic
When Formatter::create replaced new_formatter, the handling of an
invalid format was also incorrectly changed. When an invalid format (for
instance "plain") was specified, new_formatter returned a NULL pointer
which was sometime handled by creating a json-pretty formatter and
sometimes differently.
A new Formatter::create prototype with a fallback argument is added and
is used if it is not the empty string and that the format is not
known. This prototype is used where new_formatter returning NULL was
replaced by a json-pretty formatter.

mds: handle heartbeat_reset during shutdown
Because any thread might grab mds_lock and call heartbeat_reset
immediately after a call to suicide() completes, this needs
to be handled as a special case where we tolerate MDS::hb having
