we are building a docker image to run the tests

inside the circleci.yaml we call something similar to `docker run pytest`

now the circleci cli tool is not present in the docker image that we build to run tests.

how can we install/inject/mount this circleci cli in our custom docker image?

Looks like there are [install instructions here](https://github.com/CircleCI-Public/circleci-cli).
