Merge branch 'metrics' into develop
Remove implicit counting for timing events.
Fix gif2video
Enable gif2video by default
Merge branch 'fix-gif2video' into develop
Track time taken to transcode GIFs
Set the 'via' response header instead of 'proxy-agent'
Add a 'x-original-content-length' response header

This contains the original 'content-length' header value which
allows the UA to determine its own total compression ratio.
Optionally (but by default) accumulate in ingress when we don't have content-length

This allows us to then write a content-length (and more importantly,
x-original-content-length).
Merge branch 'header-stuff' into develop
Fix the build
Added code coverage command.
Delay post-processing and caching for quick response.
Fork plugin on by default in production only.
