mon: Monitor: make 'quorum enter/exit' available through the admin socket

If we don't have at least 'quorum enter' available through the admin
socket, then we can never tell a monitor to go back into quorum after
exiting, since it will not handle the command that forces it back in due
to not being in the quorum.

qa: workunits: mon: ping.py: test 'ceph ping'

Basic testing by forcing each monitor out of quorum at a time and making
sure they still reply to ping requests.

mon: OSDMonitor: drop cmdval_get() for unused variable

We don't ever use any value as a float, so just drop obtaining it.  This
makes it easier to partially revert 2fe0d0d9 in an upcoming patch.

mon: OSDMonitor: receive CephInt on 'osd pool set' instead on CephString

This partially reverts 2fe0d0d9 in order to allow Emperor monitors to
forward mon command messages to Dumpling monitors without breaking a
cluster.

The need for this patch became obvious after issue #6796 was triggered.
Basically, in a mixed cluster of Emperor/Dumpling monitors, if a client
happens to obtain the command descriptions from an Emperor monitor and
then issue an 'osd pool set' this can turn out in one of two ways:

1. client msg gets forwarded to an Emperor leader and everything's a-okay;
2. client msg gets forwarded to a Dumpling leader and the string fails to
be interpreted without the monitor noticing, thus leaving the monitor with
an uninitialized variable leading to trouble.

If 2 is triggered, a multitude of bad things can happen, such as thousands
of pg splits, due to a simple 'osd set pool foo pg_num 128' turning out
to be interpreted as 109120394 or some other random number.

This patch is such that we make sure the client sends an integer instead
of a string. We also make sure to interpret anything the client sends as
possibly being a string, or an integer.

mon: OSDMonitor: don't crash if formatter is invalid during osd crush dump

Code would assume a formatter would always be defined. If a 'plain'
formatter or even an invalid formatter were to be supplied, the monitor
would crash and burn in poor style.

Backport: dumpling, emperor
We didn't init this member variable, which might cause that when
modifying user info that has this flag set the 'system' flag might
inadvertently reset.
