Subject: [PATCH] Add Dell Storage Center Cinder extra spec info

The volume type extra spec storagetype:storageprofile
can now be used to allow volumes to be created with
Storage Profiles other than the default.

This patch adds documentation around what this feature
is and how to configure it using the extra specs.

This documents a new feature for Liberty.

+    <para>Storage Profiles control how Storage Center manages volume data.
+      For a given volume, the selected Storage Profile dictates which disk
+      tier accepts initial writes, as well as how data progression moves data
+      between tiers to balance performance and cost. Predefined Storage
+      Profiles are the most effective way to manage data in Storage
+      Center.</para>
+    <para>By default, if no Storage Profile is specified in the volume extra
+      specs, the default Storage Profile for the user account configured for
+      the Block Storage driver is used. The extra spec key
+      <literal>storagetype:storageprofile</literal> with the value of the name
+      of the Storage Profile on the Storage Center can be set to allow to use
+      Storage Profiles other than the default.</para>
+    <para>For ease of use from the command line, spaces in Storage Profile
+      names are ignored. As an example, here is how to define two volume
+      types using the <literal>High Priority</literal> and <literal>Low
