Shell scripts to manage multiple Tomcat instances

In order to simplify the deployment complexity of Tomcat, the previously individually configured script was presented as a parameter that can be used for multi-tomcat instance management in a stand-alone environment.

Where the Deploy feature will rename the specified module war to be backed up by datetime and then deploy a new war

The command line format is

Tc. SH [Tomcat_location] {Status|start|stop|restart|jstat|deploy} [Module_name]
