Subject: cli: add live management commands

Add command to install the files of a live system. Example:
ogcli install live --name ogrelive-6.1.0-26

Perform an update if live files are already present.

Add command to delete the files of a live system. Example:
ogcli delete live --name ogrelive-6.1.0-26

Update ogcli list live to show the lives in the server when
invoked with the --remote flag. Example:
ogcli live live --remote
