intelmqsetup: should install a default state file

[sebix]

Currently, intelmqsetup calls intelmq upgrade-config also on new installations. This results in a lot of "nothing to do" migrations:

Calling `intelmqctl upgrade-config` to update/create state file.
Writing initial state file.
Successfully wrote initial state file.
Found no previous version or forced, doing all upgrades.
Upgrading to version 1.0.0.dev7.
Migrate modify bot configuration format: Nothing to do.
Upgrading to version 1.1.0.
Replace deprecated Shadowserver feednames: Nothing to do.
Checking for deprecated runtime configurations (stomp collector, cymru parser, ripe expert, collector feed parameter): Nothing to do.
Upgrading to version 1.1.1.
...

and so on.

Instead, for new installations, an "empty" state.conf file should be created, like we do it with the packages: https://build.opensuse.org/package/view_file/home:sebix:intelmq/intelmq/state.json?expand=1

• it needs to be checked if the file already exists
• if yes: continue with current code
• if not: create the file with the current version as sole entry in version_history (see link to the example above) and correct file permissions
• continue with current code
