Expose Toxiproxy control port and proxy name (#3454)

* Expose Toxiproxy control port and proxy name

In order to work with and external Toxiproxy client we need the control
port to get the mapped port and the proxy names to interact with.

* Accessor for Toxiproxy mapped control port

Hidden the port constant again and created accessor for Toxiproxy
mapped control port.
