Merge cloudfoundry comunity fixes

Via this pull request I would like to merge the fixes which I have done in [cf-community/cf-services-contrib-release](https://github.com/cloudfoundry-community/cf-services-contrib-release/compare), in order to remove that repo.
I think I would be better to have one single repo for the contrib services and believe this should be the one hosted in the cloudfoundry organization.

I have merged all changes + have applied patches for fixes which where done in [cf-services-contrib](https://github.com/cloudfoundry-community/cf-services-contrib).

Before this PR can be merged the [rootfs/lucid64](https://github.com/cloudfoundry-community/cf-services-contrib-release/blob/master/config/blobs.yml#L77-L81) blob should be added. But I don't yet have access to the blob store.
