Update aks module to output identities

[jpflueger]

These changes use the azurerm_kubernetes_cluster resource's attributes as outputs instead of using the azure cli to get the desired outputs. It also exports the oms_agent_identity which will be required for a future improvement to the use of managed identity.

I was able to provision the azure-msi environment using this branch. Are there other tests that I should be running? Sorry, not sure what the process is for bedrock testing.

It looks like the automated tests may be hung, let me see what I can do about that.

@jpflueger - did you try running the tests in bedrock/tests? The pipeline seems hung, I will take look when I get a chance.
