Review Comment:
We don't check for ordering here, it's expecting the value of this key to be
exactly the same order as its sent in which it should since it's just a string
value

> Fix config setup to Opentelemetry metric emitter
> ------------------------------------------------
>
> Key: GOBBLIN-2053
> URL: https://issues.apache.org/jira/browse/GOBBLIN-2053
> Project: Apache Gobblin
> Issue Type: Improvement
> Reporter: William Lo
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Opentelemetry event submitter which is used in GaaS was not propagating
> certain tags and attributes correctly to connect to external sources.
> We want to do the following:
> 1. Add some logging when the emitter is initialized successfully
> 2. Enforce a URL if it is enabled so that it can emit to an endpoint (not
> localhost)
> 3. Allow the user to specify headers in JSON format for forwarding metrics to
> a metrics aggregator (e.g. Fluentbit)
