Is your feature request related to a problem? Please describe.

Not so much a problem, but would provide an optimization. We currently use a transformation to accomplish this and it would just be one less block of config to setup.

Describe the solution you'd like

In envoy there's an ability to extract a sub section of a cookie to grab a jwt token. Currently you all have from_headers but it'd be nice if you could also implement this.

Describe alternatives you've considered

As stated above we currently use a transformation as an extra step to achieve this so it's a nice to have to do one less step.
