Window's "datalab create" causes the Putty client to baulk at "-o LogLevel=error"

[jayprich]

Command: datalab connect --verbosity debug --max-reconnects 0 tat-dl
Symptom: the Putty Windows app throws up a dialog complaining "-o" is an unrecognised argument
Excerpt from trace:
DEBUG: Executing command: ['C:\Users\tatli\AppData\Local\Google\Cloud SDK\google-cloud-sdk\bin\sdk\putty.exe', '-t', '-i', 'C:\Users\tatli\.ssh\google_compute_engine.ppk', u'-4', u'-o', u'LogLevel=error', u'-N', u'-L', u'localhost:8081:localhost:8080', u'datalab@104.155.126.40']
DEBUG: (gcloud.compute.ssh) [C:\Users\tatli\AppData\Local\Google\Cloud SDK\google-cloud-sdk\bin\sdk\putty.exe] exited with return code [1].

Note that omitting "-o LogLevel=error" successfully opens an SSH tunnel

This is a duplicate of #1356

A fix will be out in the next gcloud update but until then the known work-arounds for this issue are:
Downgrade to version 153.0.0 of the Cloud SDK, or
Use the Cloud Shell to run datalab connect
