Rebind problems

[Svetoslav Neykov <sv...@cloudsoftcorp.com>]

Current master of Brooklyn hits rebind errors when rebinding against a previous version. The main problem is with the upgrade of gson library done in [ <https://github.com/apache/incubator-brooklyn/pull/661>1] where the implementation used for maps has been changed. To work around the problem the state needs to be updated to the new representation.
To update the state:
  * copy the attached files transform-gson.xslt and transform-gson.yaml on the machine where Brooklyn is running
  * update the path in transform-gson.yaml to point to the location of transform-gson.xslt
  * move the persistence folder to a new location
  * execute bin/brooklyn copy-state --persistenceDir <path to old persistence, ~/.brooklyn/brooklyn-persisted-state/data-old> --destinationDir <path to persistence folder, ~/.brooklyn/brooklyn-persisted-state/data> --transformations=<absolute path to>/transform-gson.yaml

Additionally two policies used to be registered in the catalog, but don't support catalog usage. Latest Brooklyn will check catalog items while loading them, so will report error if they are present. To avoid warning messages in the web console remove them from the persistence folder:
  * catalog/brooklyn.policy.followthesun.FollowTheSunPolicy_0.0.0.SNAPSHOT
  * catalog/brooklyn.policy.loadbalancing.LoadBalancingPolicy_0.0.0.SNAPSHOT
