Runs the server status script which tells the Patching Tool if the application
server is running. The server status is checked before "install" and "revert"
commands to avoid data corruption if the "server.status.script" is configured in
the properties file.

This script is not shipped with Liferay or the Patching Tool, you will need to
create one according to your environment and application server's configuration.

Patching Tool checks the exit value of this script. If it is "0" then it informs
the tool that the server is not running. Any other values are interpreted as the
server is not stopped.

This command is useful for testing the script.
