Add compute-servers-create-multiple as advisory

This patch adds a new capability for Nova: the "create multiple
servers" API [1], which allows a user to create multiple servers with
a single API call.  Although this API is not widely used by tools such
as gophercloud, libcloud, or Terraform, it meets most other criteria
and is not specific to any particular backend.

 Notes:
+  * compute-server-create-multiple is not widely supported by 3rd party
+    SDK's and tools at this point.  As examples, it does not appear to be
+    supported by gophercloud, libcloud, or Terraform.
   * compute-servers-suspend-resume is not widely supported by
     different hypervisors, and is not recommended as a capability.
   * There has been some discussion that this capability is not widely
