client: enable configuration of client response interface

Default ClientResponse implementation locks down access to the raw
response, which causes difficulty in debugging outside of debug logs.

Opening up the configuation gives flexibility to those that need it,
while keeping the default for backwards compatability.  Current users
will not need to make any changes.
