Java 11 packages conflict

**Describe the bug**
When using the library on Java 11 with modules enabled you get the following error:

Module “mymodule” reads packages “com.microsoft.azure.cosmosdb.rx.internal” from both ‘azure.cosmosdb’ and ‘azure.cosmosdb.commons’

**To Reproduce**
Create a module that uses the library and requies both azure.cosmosdb and azure.cosmosdb.commons.

**Expected behavior**
Each library should not have classes that share the same package.

**Actual behavior**
Unable to compile.

**Environment summary**
SDK Version: 2.6.1
Java JDK version: Java 11
OS Version: OSX but OS independent.
