fixes vmware-archive#105

This feature adds support to alert on specific event type per resource.
For example, to watch only create and update events on deployment resource, kubewatch.yaml should be
 resource:
  deployment:
    watch: true
    events:
      create: true
      update: true
      delete: false
This also adds custom event type 'loadbalancercreate' to notify when there is a loadbalancer created for a service.
 resource:
  services:
    watch: true
    events:
      create: true
      update: true
      delete: true
      loadbalancercreate: true
