Guard Block/Station

There should be a feature which Iron Golems and other mobs will hover/linger around blocks. This feature will allow players to force Iron Golems to essentially "guard" areas. A player could make a fortified village with Iron Golems loosely stationed around the edges to protect the area. As well, other mobs like the Copper Golem and Snow Golem could be frozen in place and forger to linger. It would allow for other mobs to also linger like pets. Dogs could use this with a carpet bed to sleep (quietly hopefully, I've noticed they bark often) and sit while Iron Golems would behave differently and walk around. It could be a later end magically item or block. I think the idea of a village with Iron Golems patrolling far out in guard stations is something that belongs in this game via vanilla.
