Returns the number of placement groups which should be specified when
creating the pool. This is based upon the calculation guidelines
provided by the Ceph Placement Group Calculator (located online at
http://ceph.com/pgcalc/).
The number of placement groups are calculated using the following:
(Target PGs per OSD) * (OSD #) * (%Data)
----------------------------------------
(Pool size)
Per the upstream guidelines, the OSD # should really be considered
based on the number of OSDs which are eligible to be selected by the
pool. Since the pool creation doesn't specify any of CRUSH set rules,
the default rule will be dependent upon the type of pool being
created (replicated or erasure).
This code makes no attempt to determine the number of OSDs which can be
selected for the specific rule, rather it is left to the user to tune
in the form of 'expected-osd-count' config option.

be contained in the pool for the specific OSD set. Default value
is to assume 10% of the data is for this pool, which is a
relatively low % of the data but allows for the pg_num to be
increased. NOTE: the default is primarily to handle the scenario
where related charms requiring pools has not been upgraded to
include an update to indicate their relative usage of the pools.
