Create TOSCA BlockStorage node type and its mapping in Heat. Introduce relationship template which will also provide a base for implementing relationship templates section in the TOSCA template. Introduce tests for generator/translator code. implements blueprint tosca-blockstorage-type Closes-Bug: #1351129 Closes-Bug: #1354632 Change-Id: I7df198ea45875031557e2607d932f14f272bf2e1
