Remove sudo from docker commands - use docker group membership instead

Agent changes:
- Changed docker ps and docker images commands to run without sudo
- cm-agent user is already in docker group, so sudo is not needed
- Fixes "unable to change to root gid: Operation not permitted" error
- Systemd security restrictions were blocking sudo gid changes

This fixes Docker container and image collection on systems with
systemd security hardening enabled.

Updated to version 0.1.178
