Busybox should be installed and managed from the ramdisk element,
since that is common to all elements that need busybox. In
addition, we do not want busybox installed when building Dracut
ramdisks, so it can't be in the deploy-* elements.

Use "deploy" to denote that an element provides the deploy
capability for a ramdisk for tripleo installation purposes.
This will be a 3-part change to enable renaming deploy to
deploy-baremetal so that the generic "deploy" capability can
be used for the provides file, as a dependant change will have to
be made in tripleo-incubator.
The tripleo-incubator change is
I1ff4bb98c99dfe87ccc4fb19767b93e27707d3a7 and that swaps to using
deploy-baremetal in place of deploy for ramdisk creation when using
baremetal.
