Add "tolerations" parameter in Kubernetes context

This new parameter, "torelations", is applied to pods and allow (but not
require) the pods to schedule onto node with matching tains [1].

Example of "tolerations" definition in a Kubernetes pod:

  spec:
    containers: [...]
    tolerations:
      - key: <key defined in the taint>
        value: <key value to match with the taint>
        effect: <effect in case of match>
        operator: <matching operator>
      - key: ...

Example of "tolerations" definition in a Yardstick test case:

  context:
    type: Kubernetes
    servers:
      host:
        containers: [...]
        tolerations:
          - key: ...
            value: ...
            effect: ...
            operator: ...

NOTE: if any toleration is defined, a default one will be applied in
order to allow any replication controller to create the pods in any
Kubernetes node. This default toleration is defined as:

  spec:
    tolerations:
      - operator: "Exists"
