can't pass booleans to service bus create_queue,create_topic,create_subscription

[huguesv]

When setting the options to pass to these functions, you have to pass in booleans as strings ie. 'false','true' otherwise if you pass in real booleans then get serialized as 'False','True' which causes a failure.

The following unit tests are affected (they currently use strings):
test_create_queue_with_options
test_create_topic_with_options
test_create_subscription_with_options

This is fixed locally and will be included in next push to github.

Verified as fixed.
