Gear Filter functionality

[Sheeri]

The Gear Filter should appear for all roles (agency admin + global admin + officer) look and act like this - including any searches: https://mongodb.invisionapp.com/console/share/VJXLVXNPGW4/587693477 - it should act the same as EMS when using search AND when checking Other - there is a Description field in the app when someone marks Other which should be searched with this. EMS design is at https://mongodb.invisionapp.com/console/share/VJXLVXNPGW4/587694089
