example catalog service classes not working with service catalog

[maleck13]

The service catalog wont allow names and ids that do not meet the regex [a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])

It returns the following error when getting the catalog:

'Error syncing catalog from Broker. Error reconciling serviceClass "mongo-db"
      (broker "mongo-service-broker"): ServiceClass.servicecatalog.k8s.io "mongo-db"
      is invalid: [plans[0].name: Invalid value: "gold plan": [-_a-z0-9]+ (e.g. ''plan_name'',
      regex used for validation is ''plan-name''), plans[0].osbGuid: Invalid value:
      "gold_plan_id": [a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])? (e.g. ''123-abc'',  or
      ''456-DEF'', regex used for validation is ''my-name'')]'

I have a pr coming to fix this.
