ubic-admin --user-config option (and --no-user-config)

[tadam]

I'm using Ubic in C++ tests, so I cannot run ubic services just using Ubic.pm. Typical workflow is:

• Run ubic-admin setup to make all needed directories in a temp directory.
• Put service files into tmp/ubic/service/
• Run Ubic providing ENV vars.
• ...
• Stop Ubic using the same ENV vars.

So far everything is OK. But on the first step I cannot avoid reconfiguration of local ubic.cfg. I'd like to have an option like --user-config and --no-user-config (similar to --crontab) to be able to turn off reconfiguration of ubic.cfg.

I don't send a patch as I don't know whether anything should be prompted for this option or not.

Another idea that I have is that instead of UBIC_DIR, UBIC_SERVICE_DIR, etc. you could have smth. like UBIC_CONFIG_FILE and all the other options would be placed in that file.

This looks sane to me. I believe you won't have to prompt for anything (except for the config file name), since --batch-mode is already a thing. UBIC_CONFIG_FILE is a good idea too.

I don't want to implement this myself, because even though the patch would be easy, I'm too lazy to write the proper tests, and I don't have any serious Ubic installations around to test it there. My perl skills are rusty... I'll gladly merge a PR, though.
