igw: Add selinux support for ceph iscsi

This adds selinux support for the ceph iscsi daemons under the ceph
github:

ceph-iscsi-config - rbd-target-gw
ceph-iscsi-cli - rbd-target-api

We use tcmu-runner, but that will go into the core policy to avoid
conflicts with gluster and distro bases.

This requires the patches:

ceph/ceph-iscsi-config#90
ceph/ceph-iscsi-cli#134
