Comment 4 for bug 1882967

This is clearly an early WIP but I do have a branch that I don't want to lose track of: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jboyer/lp1882967_external_tls_wip / working/user/jboyer/lp1882967_external_tls_wip
It currently allow me to put nginx in front of apache and not use SSL between the two. It does *not* yet allow Evergreen to work over plain port 80 http so it's clearly incomplete but it is a start.
