[Resource] PolicySet test will not re-record and does not unwrap service error

[tjprescott]

The test test_resource_policyset will not re-record. It fails on Bad Request when trying to create the policy assignment with the newly created set-definition. The test has been marked with @live_only to unblock unrelated changes in Network.

There are two issues:

1. The policy assignment create step in the test fails.
2. The command does not properly unwrap the error from the service. Running the command manually with --debug I got the following error trace:

msrest.http_logger : b'{"error":{"code":"InvalidPolicySku","message":"The policy assignment \'<null>\' is 
invalid because it references a policy set definition (\'/subscriptions/0b1f6471-1bf0-4dda-aec3-
cb9272f09590/providers/Microsoft.Authorization/policySetDefinitions/test-policy1\') and has missing or 
unsupported Sku: \'{\\"name\\":\\"A0\\",\\"tier\\":\\"Free\\"}\'. To assign a policy set definition, use one 
of the following SKUs which support this feature: \'[{\\"name\\":\\"A1\\",\\"tier\\":\\"Standard\\"}]\'."}}'
msrest.exceptions : Operation returned an invalid status code 'Bad Request'

So the test should be fixed, but also the exception handler should be fixed to unwrap and expose this error.

I ran the test again and found that the problem could not be repeated. I will remove @live_only to add this test case to the CI process.
