Updates hadoop-hdp to use new project name in URL

This patch modifies the download URL used in the
  hadoop-hdp/source-repository-hadoopswift file to use a URL that
  includes the new project name.
This change is required by the project renaming effort, and the
  Hortonworks URL for this rpm is already available.  This change
  references the updated URL.
