Capture timing of requests

[nmck257]

(I'm new to Hoverfly)

Is your feature request related to a problem? Please describe.
I think Hoverfly could be useful not just for unit testing, but performance testing.
In (some forms of) performance testing, I would like to stub out my application's connections to downstream webservices and return fixed responses, but with realistic (data-driven) delay.

Describe the solution you'd like
Could Capture mode be enhanced to grab not only request/response, but also the time taken for the roundtrip? This data could (minimally) be read by the developer to better-inform "hardcoded" delays, or a step further, could feed directly into Simulate mode.

Describe alternatives you've considered
Manually researching and configuring delays for requests.

As a starting point, we can record the latency as fixed delay in capture mode. It seems easy to implement.

@tommysitu can I pick this up?

@kapishmalik of course if you have time. Thank you!
