Updated the following in the ErrorSim:
1) Cleaned up the print information formatting
2) Added the user interface to select which option they want to operate
the ErrorSim in
3) Implemented the different operation modes (Lost, Delayed, Duplicated)
4) Modified the run method in the ConnectionManagerESim to clean up the
Normal operation
5) Changed the SERVER_PORT to use the port 69 at the initial request and
then the server port that it received the packet from 

KNOWN ISSUES:
1) Shut down only works at the beginning. This is due to the user input
only working at the beginning of the ErrorSim creation. Will update this
to have it ask for the user input at each new request
