[aws-for-fluent-bit] Adding common tollerations to aws-for-fluent-bit daemonset

[vumdao]

In my Kubernetes cluster, almost the nodes are added taints, when I install aws-for-fluent-bit it was just installed on 2 nodes which are not tainted.

⚡ $ ks get daemonset
NAME                                            DESIRED   CURRENT   READY   UP-TO-DATE   AVAILABLE   NODE SELECTOR                 AGE
aws-for-fluent-bit                              2         2         2       2            2           <none>                        29m

The aws-for-fluent-bit chart should have default toleration to support deploy the pod on all nodes, for example.

      tolerations:
      - effect: NoSchedule
        key: node-role.kubernetes.io/master
        operator: Exists
      - effect: NoExecute
        operator: Exists
