LGTM. But it'd be great if someone else from my team also takes a look as I'm still new to integrations.

@bhapas : What is criticality of this change ?
Since for couple of integrations we are jumping from 8.3 to 8.7 (big jump). We might have to evaluate that

@ishleenk17 This change would enable the users of the integration be able to enable request-response tracing between the host and the agent. This would be helpful in debugging the issues as these logs are part of agent diagnostics.

Not sure about the big jump though... We are already on the 8.8 of stack and any new feature in beats shall only be on 8.7 (8.7.2)or above. What else do you think would cause an issue?
