Use this middleware and its helpers to accumulate custom New Relic
metrics on a per-request basis.  If, while handling a request, the app
does not accumulate any metrics, this middleware is a very lightweight
no-op.

This commit also enables the middleware!

PERF-354

This specifically enables/disables the underlying comment service client
used to make calls to the service.  When disabled, this client will now
throw an exception which can be propagated upwards so that callers can
make the right decision about how to notify users of the error, or
handle retry, etc etc.

TNL-5084

This reverts commit 21746f1e.

* visit() already does a wait_for_page()
* wait_for_page() already asserts on is_browser_on_page(), as it will raise a BrokenPromise after polling
* don't use is_browser_on_page() in an assertion unless you are 100% certain you're already on the page
* if an action takes you to another page, synchronize with a wait_for_page() for that new page

Also update JIRA tickets.
