Record response time at response end instead of response start

[bobwei]

Should record response time at response end instead of response start so that we can record whole response time for streaming response.

[dougwilson]

Thanks! Can you add this as an option instead of changing the behavior?

[dougwilson]

Also the docs need to be updated (though since this should be a new option, add new docs). Here is the current docs:

:response-time[digits]
The time between the request coming into morgan and when the response headers are written, in milliseconds.

Hi @dougwilson , thanks for your suggestion !

changed made to pr

[dougwilson]

Hi @bobwei sorry I never came back to this PR. I just realized that instead of landing this as a flag that changes the behavior of an existing token, we should modify the PR to just add a new token with the behavior, which same the same ultimate outcome, but the benefit of being able to include both of these times in the output if that's desired.

[dougwilson]

I have just written all the code to move this to a :total-time token. If you are agreeable on this approach, I can squash this into your PR here and merge as your PR still.

[bobwei]

Hi @dougwilson, sure, please proceed.

Can this be merged please?
