[FEATURE] Enable SSL Cert Linkage

[Keith Gamble]

Is your feature request related to a problem? Please describe.
Currently the gateway uses http by default, but if we added in a way to place a symlink to a certain directory, we could map ssl cert contents into the gateway and tell the gateway to use https by default. This would allow the use of OAuth providers and anything that needs a callback.

Describe the solution you'd like
I imagine something like:

• Create your cert and accept it with these X steps
• Create a symlink into the container with something like /certs
• Check the /certs directory for contents during startup, if present then create a symlink into the right directory on the gateway
• Maybe need to set some configuration values automatically to enable tcp/ssl?
