Under the convoluted code path for the transport configuration,
TLSConfig was being set even though the socket type is unix. This caused
other code detecting the TLSConfig to assume https, rather than using
the http scheme. This led to a situation where if `DOCKER_CERT_PATH` is
set, unix sockets start reverting to https. There is other odd behavior
from go-connections that is also reproduced here.
For the most part, we try to reproduce the side-effecting behavior from
go-connections to retain the current docker behavior. This whole mess
needs to ripped out and fixed, as this pile spaghetti is unnacceptable.
This code is way to convoluted for an http client. We'll need to fix
this but the Go API will break to do it.

This package doesn't really seem to do anything of real interest.
Removing it and replacing with a few helper functions. Most of this was
maintaining a fork of ctxhttp to support a mock that was unnecessary.
We could probably do with a further refactor of the client interface.
There is a lot of confusion of between transport, http layer and
application layer that makes for some awkward code. This change
improves the situation to the point where no breaking changes are
introduced.
