Message:

Add more detailed wait time information to EWS metrics
​https://bugs.webkit.org/show_bug.cgi?id=137649

Reviewed by Daniel Bates.

Added average and worst time (we used to only have median), and also a percentage
of patches that took a non-trivial time to start. Non-trivial is defined as 3 minutes.

There is always some wait due to the polling nature of the queues, which is well understood
and doesn't need to be measured. What needs to be measured is whether there is enough
bot machines to process patches as soon as they are submitted.
