Kyle Bader cd0eddc460 rgw: add cpuset support 
1/ The OSD already supports cpuset to be used for containerized deployments
through the use of the ceph_osd_docker_cpuset_cpus variable. This adds similar
support to the RGW service for containerized deployments by setting a new
variable named ceph_rgw_docker_cpuset_cpus. Like the OSD, there are times where
using distinct cores has advantages over using the CFS in kernel scheduler.

ceph_rgw_docker_cpuset_cpus accepts a comma delimited set of CPU ids

2/ Add support for specifying --cpuset-mem variable to restrict the cgroup's memory
allocations to a particular numa node, which should typically correspond with
the cpu ids of that numa node that were provided with --cpuset-cpus. To ensure
the correct cpu ids are used one can run `numactl --hardware`  to list the nodes
and which cpu ids correspond to each.
