Logging the sunbeam command - [feature request supportability]

[Marcin Wilk]

Every execution of the 'sunbeam' command creates a distinct log file under $HOME/snap/openstack/common/logs/ directory. Although it is possible to analyze a log file to get a grasp of which particular sunbeam subcommand was executed, but it will be way more convenient for troubleshooting if every logs starts with the exact copy to the full command string including all the parameters provided. For example, after running:
'sunbeam cluster bootstrap'

the corresponding log could start with something similar to the following:
07:37:14,426 root DEBUG Logging to '/home/ubuntu/snap/openstack/common/logs/sunbeam-20240606-073714.425891.log'
07:37:14,426 sunbeam.provider.commands DEBUG Running "sunbeam cluster bootstrap" ...
...

This is a fairly simple request that would really help debugging sunbeam, here's the proposed change: https://github.com/canonical/snap-openstack/pull/248
