In addition even if value is set within the range lets say 3 in cloud it creates it as 1/3 so in anyway the field streaming_units = xx is not working as expected in anyway

FYI: After some playing around and look at Azure responses it turns out that Streaming Units on API level is instance count, therefore streaming_units filed works as follows:
3 Instance count is = to 1/3 of V2 Pricing SU
7 Instance count is = to 2/3 of V2 Pricing SU
10 Instance count is = to 1 of V2 Pricing SU and so on. Using Instance count numbers on streaming_untis field result in proper sizing in the cloud. Closing maybe will be ideal for some description and update on the TF documentation for first time users.
