Deprecate Ceilometer Expirer

We dont need expirer unless we have collector and standard
storage enabled. Lets turn it off by default and make it
an optional service. In upgrade scenario, we will kill the
process and stop the expirer, unless explicitly enabled.

+upgrade:
+  - With expirer deprecated and disabled by default, there is an upgrade
+    impact here. If you had expirer enabled in ocata and you upgrade to
+    pike the expirer will not be enabled anymore. If you wish to use
+    expirer, ensure you include the ceilometer-expirer.yaml
+    to your upgrade deploy command. Also note that with collector
+    disabled, there is no need for expirer to be running.
+deprecations:
+  - Deprecate and turn off expirer service as collector. Without collector
+    and standard storage, expirer has no use.
