setdiscovery: stop limiting the number of local head we initially send
In our testing this limitation provides now real gain and instead triggers
pathological discovery timing for some repository with many heads.
See inline documentation for details.
Some timing below:
Mozilla try repository, (~1M revs, ~35K heads), discovery between 2 clones with
100 head missing on each side

Private repository (~1M revs, ~3K heads), discovery from a strip subset, about
100 changesets to be pulled.

Error is handled reasonably. We override the phabtoken here so that
when you're developing changes to phabricator.py you can edit the
above config and have a real token in the test but not have to edit
this test.
$ hg phabread --config auth.hgphab.phabtoken=cli-notavalidtoken \
> --test-vcr "$VCR/phabread-conduit-error.json" D4480 | head
abort: Conduit Error (ERR-INVALID-AUTH): API token "cli-notavalidtoken" has the wrong length. API tokens should be 32 characters long.
Basic phabread:

# HG changeset patch
exchangev2: start to implement pull with wire protocol v2
Wire protocol version 2 will take a substantially different
approach to exchange than version 1 (at least as far as pulling
is concerned).
This commit establishes a new exchangev2 module for holding
code related to exchange using wire protocol v2. I could have
added things to the existing exchange module. But it is already
phabupdate with an accept:
$ hg phabupdate --accept D4564 \
> -m 'I think I like where this is headed. Will read rest of series later.'\
> --test-vcr "$VCR/accept-4564.json"
