debugcommands: support sending HTTP requests with debugwireproto
We implement an action that can issue an HTTP request. We can define
headers via arguments and specify a file to use for the HTTP request
body.
The request uses the HTTP peer's opener, which is already configured
for auth, etc. This is both good and bad. Good in that we get some
nice behavior out of the box. Bad in that some HTTP request headers
are added automatically.

#if bundle1
Bundle1 works because a) phases are updated as part of changegroup application
and b) client checks phases after the "unbundle" command. Since it sees no
phase changes are necessary, it doesn't send the "pushkey" command and the
prepushkey hook never has to fire.

Bundle2 sends a "pushkey" bundle2 part. This runs as part of the transaction
and fails the entire push.
