Add timeout when asking whether to rebuild image (apache#17412)

This PR adds timeout to answer the question, whether to rebuild
image when `breeze` is invoked or when pre-commit is run.

This reflects the typical use cases where rebuild is mostly not
needed, only in case of some tests which require new dependencies
to be included.

User has still 4 seconds to answer Y and have the images rebuilt
and just the presence of the question will be enough to get the
user trigger it from time to time.
