debugcommands: ability to suppress logging of handshake

The tests for calling wire protocol commands were getting quite
verbose because they included the results of the capabilities
request. Furthermore, it was annoying to have to update several
tests every time the capabilities response changed.

The only tests that really care about the low-level details of
the capabilities requests are those testing the protocol
handshake. And those are mostly not instantiating peer instances
or are contained to limited files.

This commit adds an option to `hg debugwireproto` to suppress logging
of the handshake. The shell helper function to perform HTTP tests
has been updated to use this by default. Lots of excessive test
output has gone away.

No arguments returns something reasonable
