Merge branch 'sxapi' into 'master'

CP-13332 CLM automation

This merge request introduces the ability to deploy a named CLM blueprint from a <prepare> block in a sequence.

Additionally some issues with the API code are fixed to enable it to operate against some of the newer REST APIs, and to handle multiple organisations by selecting the last in the list not the first.

Tested in jobid 1230888 (some minor changes made following this to cleanup the MR)
