[openqa-revtui] -c parameter should support multiple files

[asmorodskyi]

./openqa-revtui -c ./_review/*.toml - suppose to consume ALL toml files in this folder

currently it is not happening

The issue is that openqa-revtui currently does not support multiple input files but only one. I consider this as a feature request and need to check if that's even possible to do.

Currently only the latest toml configuration file is considered, we should try to improve this.

Based on the current commit 93d1ab7:

• We have a singleton Config class which holds all configuration parameters
• This class only allows one instance URL
• We could add more job groups there (added by each file) but that would still not allow multiple different instances

We would likely to contain all relevant attributes in a new datastructure and create a slice of them in the Config class. I'm leaving this here for now, as this requires further investigation if the feature is feasible or not.

We should just add tabs, one for each config file.
