The Blazar CLI doesn't support show, update and delete host operations with hostname. It only accepts id because host uses a key called hypervisor_hostname, rather one called name like for leases. This patch enables the Blazar CLI to support hostname as well. Change-Id: I3a7a3307099ed518d89de37039f9366770a21ce2 Closes-Bug: #1702266
