This replaces the stax-sdk formula. This SDK is the next iteration of the
stax-sdk, and it has been rebranded cloudbees-sdk due to stax merging with
CloudBees. See https://cloudbees.zendesk.com/entries/414109-cloudbees-sdk and
ttps://cloudbees.zendesk.com/entries/420548-stax-migration-faq for details.
