wireproto: crude support for version 2 HTTP peer
As part of implementing the server-side bits of the wire protocol
command handlers for version 2, we want a way to easily test those
commands. Currently, we use the "httprequest" action of `hg
debugwireproto`. But this requires explicitly specifying the HTTP
request headers, low-level frame details, and the data structure
to encode with CBOR. That's a lot of boilerplate and a lot of it can
change as the wire protocol evolves.
`hg debugwireproto` has a mechanism to issue commands via the peer
interface. That is *much* easier to use and we prefer to test with
that going forward.
This commit implements enough parts of the peer API to send basic
requests via the HTTP version 2 transport.
The peer code is super hacky. Again, the goal is to facilitate
server testing, not robustly implement a client. The client code
will receive love at a later time.
