OPS-32 Release version 2.4

OPS-32 Release version 2.4

Fixing build-only services couldn't be built

DE-6822 control build pulls images that can't be built

Using a better method to get branch name and commit hash

The previous method broke if git ever packed refs. So now rather than
opening files inside of .git we ask git to give information. This should
also survive git version changes

version bump to 2.2.3

forgot to version bump to 2.2.2

version bump to 2.2.1

adding an --as-me option to run the container as a user rather than root

Added dump to open and command functions

Needed to do this so that I could diagnose why cat wasn't holding the
container open.
