Include 3rd party licenses in the published container images

[hessjcg]

Feature Description

We should distribute copies of this license as well as all 3rd party licenses in software distribution bundles like container images.

The cloud-sql-proxy-operator downloads all 3rd party licenses and bundles them into the container image. We could do something similar in this repo. See: cloud-sql-proxy-operator/Makefile
