Made AdapterServer and VMMagaerServer dynamically load the correct adapter and manager server based on command line arguments.

 - Separated out create_vm and init_vm, so the CentOSVZAdapter and DummyAdapter also had to change to reflect this change in semantics
 - DesktopAdapter can now be written with minimal annoyance
changed semantics of init_vm
Removed large blocks of comments in DockerAdapter
Removed the DockerAdapterServer (deprecated now)
dummy suite fully functional :)
changed makefile to reflect new semantics
removed the dummy VMManager server
