Fall back to current deployment dir for remotedeploy

Fall back to using ApplicationContainer#current_deployment_datetime in
'gear remotedeploy' if it's not specified. This should allow Jenkins
jobs created prior to the deployment enhancements to continue
functioning, albeit not 100% functional as far as deployment metadata
goes.
Use do_command with gear binary-deploy

Use do_command with gear binary-deploy so exceptions are handled in the
same manner as the other commands.
