Unable to select existing subnet using the latest merge that includes the --subnet-name flag

[jmmaldonado]

As of today the merge that includes the --subnet-name flag is not surfaced in the SDK
I have cloned the repo and executed the following command:

./datalab.py create --network-name eci-vpc --subnet-name default --no-connect --verbosity debug --zone europe-west1-b datalabvm01

The default subnet exists as can be seen by executing manually the gcloud command:
gcloud compute networks subnets describe default --region europe-west1

However the datalab create command fails as apparently it does not pass through the --region flag to the gcloud compute command, whether it is specified as the --zone flag in the datalab command, or it is selected via the interactive prompt of the datalab create command

SubnetException: Failed to find the subnet default.

Ask a project owner to create it for you, or double check your gcloud config for the correct region.
