Breaking release, with support for multiple targets from one exporter.
Now has a form to submit for a target, similar to the snmp-exporter

Big thanks to @andrekully for the refactoring, I only did smaller changes and fix the github actions.

Try updated go-release-action

Release 1.1.0

Contains improved logging, and error handling.

Now at the start the switch is tried to be reached, and aborted if it's not reachable.
The startup is properly logged, and connections to the switch are also proper logged.

An error while connecting to the switch, no longer results in a panic
