Description

Add the ability to run the web server in HTTPS.
Added the following Command Line Parameters

Motivation and Context

This allow the server to be run in HTTPS mode. This allows the web server to be run in home labs with out the "insecure" marking in the web browser.

How Has This Been Tested?

I have downloaded / built the application and executed it both with the --enable-tls flag added and it left out.
I have verified that It will stand up in HTTP mode when the flag is not added and It will stand up in HTTPS using the passed cert files when the flag is passed.
I have also modified the code so that the initial launch of the web browser will load the proper protocol.

Run on standard Ubuntu Linux environment.

Code changes are limited to adding arguments and modifying how the web server is started. Unintended consequences are also limited because the code changes are inside an if statement that can be disabled via a command line flag.

I Wanted to check on this, It seems like the test that is failing is due to something other than the code I added. However I wanted to check and see if there is anything I should be doing to trouble shoot / fix the failed test?
