This allows you to set the endpoint-type protocol globally for all
services, e.g. internaluri can be http, and publicuri can be https.
You will no longer have to specify it per service, although those
settings already exist and have not changed.
This patch changes no functionality for existing installs or deployments
and the values are defaulted to be the same as before, but allows these
values to be adjusted on a per-endpoint type basis.
