Merge pull request #1162 from greenqloud/pr-no-start

Add support for not (re)starting server after cloud-setup-management.This adds an option to the cloud-setup-management script to not start the management server after a successful configuration of it.

The primary motivation for this is to avoid circular dependency issues on systems that use systemd. When calling cloud-setup-management from a unit with a Before= directive on a service depending on
cloudstack-management, the process will deadlock because /usr/bin/service will delegate to systemd, which is waiting for the Before service to start.

Executing the cloud-setup-management script with this new `--no-start` option will simply leave the management server stopped after a successful configuration. systemd can then be bypassed with `export _SYSTEMCTL_SKIP_REDIRECT=1` and using the init.d script.

* pr/1162:
  Add support for not (re)starting server after cloud-setup-management.
