Capture data for huge page bloat monitoring

[aneeshdurg]

This PR adds the necessary infrastructure to monitor the memory subsystem to determine if bloat is occurring when using huge pages.

@arthurp this PR also requires nc to be installed in the docker container. So far I've been working around that by running:

apt update && apt install netcat-openbsd

on container startup. I could add this to the setup script for benchmarking, but how can I just add nc to the container image itself?

Let's just add it to the container. You can add it to the Dockerfile. We need to update the image version and the images we use for the builds anyway, so as soon as you add it, I can update the image in dockerhub and the version used by the build.
