Allow to split the image registry and the repository

[aacevedoosorio]

The current helm chart allows to set a global.imageRegistry in combination with the repository configured. But it would be nice as well to split the repository into the default registry for charts that use the open-telemetry chart as a subchart and have a default predefined repository.

Please run make generate-examples CHARTS=opentelemetry-collector

We don't need a new example, but can you share the output of the image string being set properly when using the new field and the global field?

I ended up creating the examples. I think they are valuable

@aacevedoosorio the new examples give me confidence that this process works, but I don't want to merge this PR with them. Using these options in the values.yaml is straight forward for an end-user even if the logic to build the string is kinda complex.

I get your point. Let me revert those examples.
