push: explicitly encode a list of obsmarkers to push

Sending obsmarkers through pushkey requires extra encoding (since pushky can't
take binary content) and slicing (since we can hit http header limit). As we
send all obsolescences markers that exists in the repo for each push, we used to
just look at the content of the "obsolete" pushkey namespace (already encoded
and sliced) and send its

However, future changeset will make it possible to push only parts of the
obsmarkers. To prepare this we now explicitly encode a list of markers. The list
of markers is still "all of them" but future changeset will takes care
of that.

The new code use a "_protected" method but that seems reasonable to keep it
private as this is the is the only external user of it and this whole pushing
obsmarker through pushkey things in fairly hacky already)
