Added network watcher APIs and tests

[irrogozh]

Description

Network SDK regenerated from a new swagger spec with added network watcher APIs.
Link to a pull request for swagger: Azure/azure-rest-api-specs#923
AutoRest version: 1.0.0-Nightly20170202
Link on swagger spec: https://github.com/Azure/azure-rest-api-specs-pr/blob/master/arm-network/compositeNetworkClient.json or
https://github.com/irrogozh/azure-rest-api-specs-pr/blob/master/arm-network/compositeNetworkClient.json

I didn't update the link in generate.cmd because I don't know which one I should use, from Azure private repo or from my own public one.

@irrogozh Hey Irina, in addition to the comment I left in the code

• you will need to update the version in project.json to whatever the version should be for release

• you will need to update the version in AssemblyInfo.cs with the same version

@irrogozh why were Compute and Storage added to this file? It looks like you are trying to use them for tests, but you already have a reference to their published packages in the Network.Tests/project.json, so you don't need to reference the path to their code in this file.
