Matthew Heler 6e8c289c13 Add failure domains, and device classes for custom CRUSH rules
Largely inspired and taken from Kranthi's PS.

 - Add support for creating custom CRUSH rules based off of failure
domains and device classes (ssd & hdd)
- Basic logic around the PG calculator to autodetect the number of
OSDs globally and per device class (required when using custom crush
rules that specify device classes).
