feat(launch): add a new --build flag for building and then pushing the image to a queue

[gtarpenning]

Fixes WB-10393

Description

When passing in the new --build flag, launch uses a URI to build a docker image and create a “Job” artifact, then pushes a run queue item that uses this job artifact to run the associated job.

Overwrites a given URI, requires the --queue flag to be set.

Testing

New test using the relay server: tests/unit_tests/test_launch_add.py
