gracefully remove flags in ._state/provisioned dir

[nfrumkin]

When unprovisioning using vc--, vcdb--, unprovision, etc., the state flags in the hpc-collab/clusters/common/._state/provisioned directory are not removed automatically (this is a new phenomena as of the past month).

We currently have to manually execute rm hpc-collab/clusters/common/._state/provisioned/* in order to reprovision.

The make target 'clean-state' (from within the clusters/vc or clusters/vx recipe directory do this.
make -C clusters/vc clean-state
and sometimes you may need:
make -C clusters/vc clean
which is a bit more thorough and removes additional files.
If using those, you may need to do a following:
make -C clusters/vc Vagrantfile
to regenerate it.
This is currently implemented in the dev branch and will be propagated to the master branch in the next major merge.

Great, is this also implemented in vc-- and such? Or should be called in addition to these aliases
