Adding devstack plugin for freezer gate job

Currently the plugin is moslty a copy of the
freeer-api plugin. At first instance we can enable
the gate and have the job executign without error,
after this we can commit new changes to execute
freezer specific tests. Anyway the freezer-api plugin
is most likley needed to execute the freezer-agent and
freezer-scheduler tests

Implements bp: freezer-dsvm
Depends-on: I837e3fe973d72c792cb34711cef9f6507a004d49

+This directory contains the Freezer DevStack plugin.
+
+To configure the Freezer scheduler and agent with DevStack, you will need to
+enable this plugin by adding one line to the [[local|localrc]]
+section of your local.conf file.
+
+To enable the plugin, add a line of the form::
+
+    enable_plugin freezer <GITURL> [GITREF]
+
+where::
+
+    <GITURL> is the URL of a freezer repository
+    [GITREF] is an optional git ref (branch/ref/tag).  The default is master.
+
+For example::
+
+    enable_plugin freezer https://git.openstack.org/openstack/freezer.git master
+
+
+For more information, see:
+ http://docs.openstack.org/developer/devstack/plugins.html
