* Add instructions on how to mount various configurations for Secure Agent so those can be re-used.
* Updated `README.md` with descriptions on how to mount volumes.
* Documented various ports in Secure Agents.
* Fixed punctuations.

Since our licensing restrict us from more than 1 instance of Secure Agent, before deploying a new instance existing instance need to be shutdown (after adjusting any resources that depends on that instance). Due to this reason terraform is not part of CI/CD.
