Add tempest test for heat resource OS::Nova::KeyPair

The template will create two OS::Nova::KeyPair and will test that:
   [*] The key with save_private_key flag set to true outputs both
       public and private keys.
   [*] The key with save_private_key flag set to false outputs
       only the public key.

Testing other cases will require to recreate the stack and
include a negative test case.
