cli: basic jj gerrit send implementation

This implements the most basic workflow for submitting changes to Gerrit,
through a verb called 'send'. This verb is intended to be distinct from the word
'submit', which for Gerrit means 'merge a change into the repository.'

Given a list of revsets (specified by multiple `-r` options), this will parse
the footers of every commit, collect them, insert a `Change-Id` (if one doesn't
already exist), and then push them into the given remote.

Because the argument is a revset, you may submit entire trees of changes at
once, including multiple trees of independent changes, e.g.

    jj gerrit send -r foo:: -r baz::

There are many other improvements that can be applied on top of this, including
a ton of consistency and "does this make sense?" checks. However, it is flexible
and a good starting point, and you can in fact both submit and cycle reviews
with this interface.
