support multiple configurations as an object not a single string

[hafizmujadidKhalid]

Hello,
I was trying to add some additional configurations such as below:

retry-policy=TASK
query.hash-partition-count=50

But it adds both properties in a single line as extraConfig: "" is a string value. We should make it an object and store all extra configuration in config.properties as it is given by the user.

This PR fixes issue #150

@valeriano-manassero!
Can you please have a look on this PR? helm-docs generation worked fine on my local but it fails on github. Error is also not explainatory to know what is going wrong actually.

[valeriano-manassero]

Pls generate README with helm-docs and commit it.

[hafizmujadidKhalid]

Thanks, Looks good now.

I'd like to see version 3.0.0 instead of 2.8.2. This is because we are in front of a potential breaking change (especially if someone already is using extraConfig).
Can you pls fix it?

@hafizmujadidKhalid Sounds like you were getting a single line string because you don't know how to use multi-line strings? Please refer to this documentation: https://helm.sh/docs/chart_template_guide/yaml_techniques/#strings-in-yaml. I've only ever seen multi-line strings used to populate data into ConfigMaps for something like this.

While this change "works" (although not implemented properly: coalesce.go:199: warning: cannot overwrite table with non table for extraConfig (map[])) it is absolutely awful in practice.

Would it please be possible to revert this change? @valeriano-manassero Thanks.

I will do another major release with rollback. Sorry I accepted the PR without having you as reviewer. Maybe I can add you next time.
