Moved the variable declarations from `functions.sh` to `arguments.sh`. We need the argument parsing before setting the logging level and other variables.
Improvements to logging:
- Logging levels as DEBUG 0 INFO 1 WARN 2 ERROR 3 REQ 4
- External logging to Datadog
- A function to shorten duplicate lines in installation logs
- Ability to extract install.log in the time when Installomator was running, if further investigations needs to be done to logs
In `logitechoptions` we do not know what the app-name is that contains the pkg in the bundle-package, so now we only give the name of the pkg, and then Installomator will find it.
When using DEPNotify I would like Installomator to return a nice name for the label to show as status in DEPNotify, instead of only the label name.
This way we can do that.
And maybe in the fute include a description of the software, if people are seeking inspiration to software by looking at Installomator (that contains a lot of preferred solution for many)
Added a bit to explanation of archiveName variable.
