with the same for docker-registry. (PR will be cited)

Splitting the exec remote API into two separate APIs inorder to support resizing of tty sessions.
1. /container/<name>/exec - Creates a new exec command instance in the daemon and container '<name>'. Returns an unique ID for each exec command.
2. /exec/<name>/start - Starts an existing exec command instance. Removes the exec command from the daemon once it completes.

Adding /exec/<name>/resize to resize tty session of an exec command.
