Support for Java client

[nkzawa]

Seems java client is stricter than node one and doesn't work properly.
Maybe we want to add integration tests with the client and ensure it works.

I am successfully conected with java but when I try to list items in collection error is shown: java.lang.IllegalStateException: com.microsoft.azure.documentdb.DocumentClientException: null, StatusCode: NotFound

Thanks for the information.
I tried to fix this once but it's still ongoing. Java client sends unexpected requests to the server and don't get why yet.

using spring data, encountering this error, it seems like the client tries to get the defaultconsistency level from cosmos, which is missing in this server
