Add support for injecting tolerations to sonobuoy pod

Resolves vmware-tanzu#1973. We can inject some tolerations to sonobuoy aggregator pod by adding trailing description into sonobuoy config json. { "AggregatorTolerations": [ { "effect": "NoSchedule", "key": "key1", "operator": "Equal", "value": "value1" }, { "effect": "NoSchedule", "key": "key2", "operator": "Equal", "value": "value2" } ] } Signed-off-by: Masashi Honma <masashi.honma@gmail.com>
