Deprecate legacy deployment elements

Browse Source 
Legacy elements deploy-tgtadm, deploy-targetcli, and deploy-baremetal
have not seen use in ages. Another element seems to date back to this,
deploy-kexec, but appears to see no actual use as the underlying methods
leveraged by these elements were long moved away from. iSCSI based
deployment being the last, and even then it required the
ironic-python-agent.

deprecations:
- |
The ``deploy-baremetal``, ``deploy-kexec``, ``deploy-tgtadm``,
and ``deploy-targetcli`` elements are deprecated and will be removed in a
future release of diskimage-builder. The origins of the elemenets largely
dates back to the early efforts to support baremetal deployment, and the
methods have been long ago moved away from.
