Remove duplicated test cases

The class ServersControllerCreateTest has the following duplicated
test cases since I091f14a9753059d759ba2f7b05ff33f5abea0f00 :

 * test_create_instance_with_config_drive_disabled
 * test_create_instance_local_href
 * test_create_instance_admin_pass_empty
 * test_create_instance_invalid_personality
 * test_create_location

This patch removes the duplicated test cases.
In addition, this removes the bookhref of test_create_location() also,
because it is not used.

xenapi: post install scriptlet to rpm

A freshly installed XenServer requires some modifications in order to be
able to run OpenStack. Nova contains an rpm specification to create a
package with the dom0 plugins, however installing the rpm is not enough.
Some more actions need to be taken:
 - create /images, link to a directory within the local SR
 - setup an ssh keypair, and authenticate it with the host
This change adds a post script to the nova plugins rpm spec file, so
by installing the rpm on a XenServer, it is ready to run OpenStack, no
further manual actions needed.
