Use the encrypted values for the user and/or keystore password when starting smart router in RHPAM

Currently, when starting smart router, the user password and keystore password are presented in clear text. This is security issue for our customers.

We need to change this so that smart router can be started using encrypted values for the user and/or keystore passwords. Also, we have to make sure that password value is not shown in the command line when running ps -ef or similar.
