logging: Add CLI command to logs

[jodh-intel]

Since the runtime is called multiple times by the container manager, add the command-line sub-command name to all log entries to make it clear which command was running when a particular log message was produced.

Note that CLI arguments are already logged once at runtime startup. This change is more useful for the scenarios where only a log excerpt is available (for example when running cc-collect-data.sh which only extracts error logs).

Fixes #1024.

@grahamwhaley - no it doesn't. That should be atleast partly possible in a follow-on PR.
