Remove USE_SSL support

tls-proxy is the way we're now doing a standard install using https
between services. There is a lot more work to make services directly
handle https, and having python daemons do that directly is a bit of
an anti pattern. Nothing currently tests this in project-config from
my recent grepping, so in the interest of long term maintenance,
delete it all.
