Make in process functional tests use sample proxy-server.conf

This patch was first motivated by noticing that the proxy
server pipeline used for in process functional tests was
out of date with respect to the pipeline in
/etc/proxy-server.conf.sample. Rather than cut and paste
the current pipeline into the in process setup, it seems
like a better idea would be to have the in process tests
always use the sample config.

A further benefit is that in process functional tests will
pick up changes to the sample config introduced by patches -
previously test/functional/__init__.py would need to be
manually modified to run in process functional tests
on new middleware for example.

Note: because the pipeline is now loaded using entry points,
'python setup.py [develop|install]' will now be needed
before running the tests.

Obvious next steps would be to do the same for the backend
servers, and to allow alternative config files and dir's
to be specified, but this patch is the first step.

Also drive-by fixes some typos in proxy-server.conf.sample
