Create virtualwarehouse may fail if multiple are requested

cloudera.cloud/plugins/modules/dw_virtual_warehouse.py

Line 417 in 90ec105

state=self.cdpy.sdk.STARTED_STATES, delay=self.delay, timeout=self.timeout

This line is susceptible to a kind of race condition where multiple virtual warehouses may be requested in cloudera.cloud, but some of them create and then auto-stop due to idleness before the full create sequence completes. This is because the 'Stopped' state is not considered a valid completion state for this wait operation.
