Ceph config option names may use spaces, underscores, or by one reference hyphens
as interstitial separators. Most usage within the doc tree uses underscores,
though example conf files and especially structured lists of options mostly
use spaces. Mostly. Underscores help differentiate the config names from
surrounding text, and moreover facilitate scripting, grep, awk, etc and match
their form in src/common/options.cc.
This PR conforms these occurrences of option names to use interstitial underscores instead of spaces.

demonstrated negligible performance impact from unnecessarily deep
directory hierarchies but significant performance impact from filestore
split and merge activity. Disable merges by default.

Store a random value up to the filestore_split_rand_factor for each
collection when it is created or apply-layout-settings is run. This
should help distribute the load of splitting directories across a
longer period of time.
