[gnome-continuous] Add 'ostbuild update indices' to regenerate indices

[Owen Taylor <otaylor src gnome org>]

commit f3f8cb25a640b4872f119c4d1909d7c92a74157d
Author: Owen W. Taylor <otaylor fishsoup net>

    Add 'ostbuild update indices' to regenerate indices
    
    To be able to retroactively have the revision => target map for
    older builds, add a new builtin that regenerates the index.json
    for each day. (It could also regenerate indices on higher levels
    if we extend those in the future - right now there is no reason
    to rebuild them, so we don't.)
