    Add some sanity to the ImageStream listener API (#32936) · 592f81e7
    Todd Volkert authored
    The current API was broken in that you registered multiple
    callbacks at once, but when you removed listeners, only the
    primary listener was used to determine what was removed.
    This led to unintuitive cases where the caller could get
    unexpected behavior.
    
    This updates the API to add and remove listeners using
    a newly introduced [ImageStreamListener] object, a value
    object that has references to the individual callbacks
    that may fire.
