the config of the ratel have no tolerations.

[cyxinda]

There are no tolerations config for the ratel in the values.yaml in dgraph helm chart.
It cause that the pod of ratel can't been schedule to some node with taint.
I add tolerations config in the values.yaml. And then ,I refer to that tolerations yaml in the file of dgraph/templates/ratel/deployment.yaml like alpha or zero.
as follow:

the helm chart version is dgraph/dgraph:0.2.2 .
