the call to os-svc-enable.

Add package support to ceilometer-alarm-notifier

Updates the ceilometer-alarm-notifier so that it supports
using distro packages via pkg-map and package-installs.
The default distro package is set to openstack-ceilometer-alarm
which on RHEL/Fedora contains the ceilometer-alarm-notifier
binary.

Also, includes the related svc-map configs so that the
packaged version of the systemd scripts work correctly.

Set lock_path in cinder.conf

Without this set, interprocess locking does not work properly.

We also need to ensure the cinder state directory is writable
by cinder, up to now it was not.
