Adding Az cli into e2e dockerfile

[rachelvweber]

Which issue this PR addresses:

https://redhat.atlassian.net/browse/ARO-23873?atlOrigin=eyJpIjoiNDhhYmYxYmVhODk1NGY1YzgzNzVkNDQxZmY0NGUwZTgiLCJwIjoiaiJ9

What this PR does / why we need it:

The e2e prow job keeps failing because the az cli isn't installed. Also, after speaking with Ben, removing entrypoint and exposing ports. We pass in the command that needs to run, and the exposed ports are unneeded.

Test plan for issue:

Tested by ci/prow/images job

Is there any documentation that needs to be updated for this PR?

No

How do you know this will function as expected in production?

I can't test this end to end until this is merged because the prow test is pointed at the master branch, but I confirmed that the image still builds correctly
