So for those first two they already exist in our Table.java API
table.expireSnapshots()
.expireOlderThan(tsToExpire)
.commit();
table.rewriteManifests()
.commit();
Only RewriteTablePath doesn't have a local version yet but I think we could
possibly add that
What were you thinking of adding to the existing apis?
