Create a keypair with public_key

Nova requires the public_key element when creating a keypair since api
version 2.92. This change ensures the element is passed when creating
a OS::Nova::KeyPair resource.

The master jobs are temporally made non-voting because one integration
test is failing now. These jobs are made voting again once the test is
fixed in the heat repo.
