Containerd populate ecs fields

[MichaelKatsoulis]

After new container ECS fields get GA (elastic/ecs#1747) containerd module need to start populating those fields.

The new fields are

container.cpu.usage
container.memory.usage
container.disk.write.bytes
container.disk.read.bytes
These fields map to containerd fields:

containerd.cpu.usage.total.pct by cpu metricset
containerd.memory.usage.pct by memory metricset
containerd.blkio.write.bytes by blkio metricset
containerd.blkio.read.bytes by blkio metricset

respectively.

Why is it important?
