feat(api): add EC2 Auto Scaling groups to the cloud explorer

Create groups from a launch template (in the default subnets unless given),
change their minimum, desired and maximum capacity, replace or remove an
instance, and follow the launches and terminations TheCloud's reconciler makes.
Deleting a group terminates its instances. Scaling policies are not offered:
the runtime stores them but its alarms only drive ECS scaling.
