Most of the state package has been deprecated by the states package. This PR replaces all the references to the old state package that can be done simply - the low-hanging fruit. * states: move state.Locker to statemgr The state.Locker interface was a wrapper around a statemgr.Full, so moving this was relatively straightforward. * command: remove unnecessary use of state package for writing local terraform state files * move state.LocalState into terraform package state.LocalState is responsible for managing terraform.States, so it made sense (to me) to move it into the terraform package. * slight change of heart: move state.LocalState into clistate instead of terraform
