[Feature Request] az pipeline build queue wait for completion

Problem: it's complex to create a simple batch file which does something when the build is complete. Currently the batch file would need to handle the json response and poll status to determine build completion.

Proposal: Add az pipelines build queue --wait-for-build-complete. Block until build completes. A non-zero exit code would be returned if build is something other than successful. Very simple to sequence in a batch file.

Example batch file / check in script might be:
git push
az pipelines build queue --wait-for-build-complete
if ERRORLEVEL 1 (
echo investigate it!!!
exit /b 1 )
git pull
init
(etc)
