Add new provision/deprovison command option

Add "--apply" command option for sm-provision and sm-deprovision
commands to apply the change to SM immediately.

If SM runtime configuration has not already been created, the new option
will not do extra. SM will load the up-to-date configuration from static
db when it creates runtime configuration.

The new commands:
sm-provision service-group-member
sm-deprovision service-group-member

will provision/deprovision both service and service group member.
The commands below are now deprecated, although they are still supported
for backward compatibility.

sm-provision service
sm-deprovision service
