Scourge Zombie hoard event

[Octane]

every 30-45 mins there would be a random spot on the map that would spawn a bunch of zombies or waves of them getting harder as starting waves finish, and maybe like the final wave is a giant zombie with alot of health and maybe a special ability.

I noticed on a different server that when I set off a supply drop  a bunch of zombies would come to it.  They need a zombie lure flare that can be set off to start a zombie horde attack.
