handle bad location for resource groups

[frodopwns]

Closes #733

What this PR does / why we need it:
Catches responses to CreateResourceGroup calls that have a code of 400. This will handle a broad range of errors but most specifically for this PR it catches the issue where a location has been requested that does not exist.

Special notes for your reviewer:

• create an RG with a location like mcdonalds make sure it fails provisioning
• create an rg you expect to succeed and make sure it does

Sadly, "The Shire" isn't an official location of Azure datacenters (yet).

Was able to create a rg with valid location successfully 👍
Was able to create a rg with invalid location and given failure message in status.message, and error in logs 👍

Except, under status when i do -o yaml, it still says provisioning = true, that should be false, right @frodopwns ?

Here is my output
status: message: 'resources.GroupsClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="LocationNotAvailableForResourceGroup" Message="The provided location ''theshire'' is not available for resource group.

Worked for me! 👍
