Error message "Loading configuration file failed." doesn't provide helpful information

[ahus1]

Problem description

When you have an invalid configuration file, there is no helpful description what is wrong.

Expected behavior: show the parser error message indicating the attribute in the configuration that can't be parsed.

Steps to reproduce the problem

1. create an invalid configuration file (in our case: mistype true/false, we had a ':' appended in here)
2. start collector
3. Error message "Loading configuration file failed." - but no information what was going wrong

Environment

• Sidecar Version: 0.1.4
