The rollover index API rolls an alias over to a new index when the
        existing index is considered to be too large or too old.

        The API accepts a single alias name and a list of conditions. The alias
        must point to a single index only. If the index satisfies the specified
        conditions then a new index is created and the alias is switched to
        point to the new alias.
