Resolves #633
When running "om vm-lifecycle create-vm" on Azure, a problem has recently occurred where querying a blob status using "az storage blob show" has started to exit with a non-zero code and error "There is currently a pending copy operation". Because of the error, the command terminates. It's likely that this is because of a change in the backend Azure API. As we are trying to determine whether the copy operation has finished, it's safe to ignore this error and continue polling.
