Remove configuration for otelcorecol

[jpkrohling]

Verify that the default config file matches the one we use for otelcorecol. If so, remove the config from the repository to rely on the default one.

The embedded default config for ocb doesn't have the "replaces" directives because in that case ocb could be running from anywhere. When you generate otelcorecol, you want the "replaces" because you know that you are building in a multi-module repo, and you want to use the local modules.

I had this suspicion and wanted to confirm this before committing to removing the config. Thanks for confirming this, looks like we should either keep the config or patch it. I would personally prefer to keep the config.

It looks like work is completed. Can we close the issue?
