Toleration for mysql cluster resource

[mtgerb]

Is this a BUG REPORT or FEATURE REQUEST?

FEATURE REQUEST

I would like to make use of the taint and toleration concept (https://kubernetes.io/docs/concepts/configuration/taint-and-toleration/) to run a mysql cluster only on specific nodes. Therefore I want to specify tolerations for the cluster kubernetes resource.

apiVersion: mysql.oracle.com/v1alpha1
kind: Cluster
metadata:
  name: mysql
spec:
  members: 3
  tolerations:
  - key: "database-node"
    operator: "Equal"
    value: "true"
    effect: "NoSchedule"

The implementation should be very similar to #218.
