Revert "Had to change the behavior of the URI concat stuff."

This reverts commit 5f59281dc884792cd0884d25c590f1e53cddefe1.
Other part of the reversion of this handling
Updated this during experimenting with the proxying failures
Comments on the ignoring
Fixed the test, and format/cleanup
Need to add these guys back in

They're part of how original repose was designed to acquire the
delegation endpoint, rather than having it happen in a servlet.

It'd probably be much less complicated to just do it in the servlet
rather than trying to handle all this fancyness.
Fixed this guy so it actually worked.

It was converted to spring, but was very broke
Just some cleaner debug logging
Updated comments and hooked up the RequestProxyService

Took me a while to figure out how this was being used. Fortunately it
works easily here within spring. There's probably other refactoring that
can be done to clean it up even more.
