confirmed-commit fixes, tests
- fixed typo preventing evaluation of confirmed-commit logic in backend_startup - fixed uninitialized variable warnings - added details to CHANGELOG.MD - added capabilities advertisement for confirmed-commit 1.0 and 1.1 - added xml hello message that uses only eom framing, for simplicity in asynch tests - add stty restore after wait_restconf to fix console corruption in tests - adjust test_confirmed_commit to drop perms and run as the invoking user. This will require running user to have permissions on /usr/local/var/example - added CLI tests
