# Set the RPM package NVR from "git describe".
# Examples:
#
#  A "git describe" value of "v2.2.0beta1" would create an NVR
#  "ceph-ansible-2.2.0-0.beta1.1.el7"
#
#  A "git describe" value of "v2.2.0rc1" would create an NVR
#  "ceph-ansible-2.2.0-0.rc1.1.el7"
#
#  A "git describe" value of "v2.2.0rc1-1-gc465f85" would create an NVR
#  "ceph-ansible-2.2.0-0.rc1.1.gc465f85.el7"
#
#  A "git describe" value of "v2.2.0" creates an NVR
