test-lfs: add tests covering http exchanges

This tries to test every combination of having the extension enabled/disabled
on each side, and then push/pull/clone/identify lfs and non-lfs content.  SSH is
ignored here, because there's enough going on as it is.

The root issue here is again that requirements are not exchanged and preserved
on push/pull/clone.  Doing so should eliminate the cryptic error messages when
using `hg serve`.  The 500 server error is triggered by "ValueError: no common
changegroup version", because the extension forces changegroup3.  Or, if
changegroup3 is enabled manually, it is triggered by "abort: missing processor
for flag '0x2000'!".

Sadly, run-tests.py doesn't support conditionalizing the exit code like it does
lines of output.  Therefore, a couple of tests blot out the exit code by
appending "|| true", since these failures will go away shortly anyway.
