ceph-disk: compatibility fix for python 3

In python 3, dev is a string, but mounts_dev is bytes (because
/proc/mounts was opened with mode 'rb') so they can't compare
equal, resulting in is_mounted() returning None for mounted OSDs.
The safest fix for this we could come up with was to normalize
dev to a str using _bytes2str() (just in case), and open
/proc/mounts in mode 'r', so its lines are interpreted as strs.

osdc/Objecter: fix split vs reconnect race

If we are reconnecting to an OSD, we may not have a connection established
so this feature check is completely unreliable.  If there happens to be a
split, that could mean we don't resend an op that should have been resent.

Instead, we can infer the OSD has the new behavior if require_osd_release
is luminous or later.  If not, we can look at the per-osd features in the
OSDMap.

mds: fix premature stop of MDBalancer::try_rebalance()

When mds wants to export loads to multiple targets. The amount of single
export can easily be less than (0.2 * target_loads). For example:

6 active mds, mds.0's load is 11, other ranks' loads are 5. target_load
is 6. Export amount for each target is 1.
