Add an initial implementation of HTTP-forwarded exec

This is heavily based off the existing exec implementation, but
does not presently share code with it, to try and ensure we don't
break anything.

Still to do:
- Add code sharing with existing exec implementation
- Wire in the frontend (exec HTTP endpoint)
- Move all exec-related code in oci_conmon_linux.go into a new
  file
- Investigate code sharing between HTTP attach and HTTP exec.
