Tim Burke 94bac4ab2f domain_remap: stop mangling client-provided paths ...

The root_path option for domain_remap seems to serve two purposes:
 - provide the first component (version) for the backend request
 - be an optional leading component for the client request, which
   should be stripped off

As a result, we have mappings like:

   c.a.example.com/v1/o -> /v1/AUTH_a/c/o

instead of

   c.a.example.com/v1/o -> /v1/AUTH_a/c/v1/o

which is rather bizarre. Why on earth did we *ever* start doing this?

Now, this second behavior is managed by a config option
(mangle_client_paths) with the default being to disable it.

Upgrade Consideration
=====================

If for some reason you *do* want to drop some parts of the
client-supplied path, add

   mangle_client_paths = True

to the [filter:domain_remap] section of your proxy-server.conf. Do this
before upgrading to avoid any loss of availability.
