Add 'server shelve --offload', 'server shelve --wait' options

The '--offload' option allows us to explicitly request that the server
be offloaded once shelved or if already shelved.

The '--wait' option allows us to wait for the shelve and/or offload
operations to complete before returning. It is implied when attempting
to offload a server than is not yet shelved.
