Remove the temporary deploy element after rename

This is dependent upon change in tripleo-incubator
I1ff4bb98c99dfe87ccc4fb19767b93e27707d3a7 and concludes the
renaming of deploy to deploy-baremetal

The rename was performed so that each element had a more descriptive
name, and so that each element could accurately set an element-provides
of "deploy", given that the elements enable tripleo deploys via the
ramdisk image.
