Abdul Rabbani 36e8711891 Test CaptureHead | Add Metrics | Handle Test Race Conditions
This Commit allows us to:

* Test the `CaptureHead` function.
* Test parsing a single Head message.
* Test a Reorg condition.
* Add Metrics. This is primarily used for testing but can have future use cases.
* Rearrange the test due to race conditions introduced by reusing a variable. `BeforeEach` can't be used to update `BC`.
