This function makes me sad but there's really no other way to handle this. We need strict unmarshaling to still work, so we have to do what prometheus does: create a merged struct of the target + all of the possible integration fields, copy defaults to the merged struct, unmarshal to the merged struct, copy original fields back to the output, and then fill in the integrations slice.
I'll try to document this more because my original look at Prometheus' code had me really confused about what was going on and why.

A go mod vendor got rid of this.
This commit adds a dynamic integration registration system similar to (and mostly copied from) Prometheus' SD registration mechanism.
1. Integration interface moved to integrations 2. Integration Config interface now responsible for providing name/config

This needs a test for marshaling; pretty sure that doesn't work with this yet. |

I haven't looked at the PR in detail, but I really like this approach 👍 that manager is getting bloated with all the integration inits. |

Ready for review again! Implemented the marshaling. |

Packages have been re-arranged since integrations can now depend on the base integrations package without a cyclic dependency.
