Matthew Heon 45a7e7266e Add bindings for exec and enable attached remote
This adds bindings for starting exec sessions, and then uses them
to wire up detached exec. Code is heavily based on Attach code
for containers, slightly modified to handle exec sessions.

Bindings are presently attached-only, detached is pending on a
Conmon update landing in CI. I'll probably get to that next.
