[ADLS] adding test_vnet_operations
ref: AutoPR

[azuresdkci]

Can one of the admins verify this patch?

@lmazuel Locally, when I ran `pytest azure-mgmt-datalake-store/tests/test_mgmt_datalake_store.py' It succeeded. I'm not sure why it failed after pushing. Any comment is appreciated

Hi @lewu-msft

First, thank you for the tests :)

I fixed your PR:

• Base branch was incorrect, since you start from a branch, when you create the PR you need to define this branch as base.
• You mixed up real credentials syntax and fake one. This will work on local machine, but not on Travis. See my last commit on your PR for details.
