This patch bakes browsers into docker image.
Important observations:
- We now re-build docker image everytime we roll browsers.
- Docker image size almost doubles: from `225MB` to `496MB`.
References #2926
This adds a new script to calculate docker image size with
all parent layers.
Note: take this metrics with a grain of salt, since in reality
docker compresses and reuses layers.
Some historic stats obtained with this script:
