We use v5 and v5.3.0 to put different python files for CDH5 and CDH5.3.0. CDH5 is CDH5.0.0, we use the name "CDH5" instead of "CDH5.0.0" for backward support. Currently since CDH5.0.0 does not support cm_api>6, we cannot use first_run API in CDH5.0.0, so we only implemented parts of the services that we implemented in CDH5.3.0. implements bp: cdh-version-management Change-Id: I3b3058f25912ddf6206d64db88ac40138a45a53f
