Azure-sdk-for-go: Support for AKS uptime SLA

[yannart]

Feature Request

Please support the AKS optional flag uptime SLA:
https://docs.microsoft.com/en-us/azure/aks/uptime-sla

Example with az cli:

az aks create --resource-group myResourceGroup --name myAKSCluster --uptime-sla --node-count 1 --enable-addons monitoring --generate-ssh-keys

Hi @yannart thanks for this issue!

I could see on azure-cli's doc page there indeed is an option --uptime-sla but after an upgrade of azure cli, I still cannot use this option.
I assume that azure-cli can implement this indicates that this feature must sit in the swaggers, therefore i want to use the debug functionality to see which this feature is called in the swagger, since I did a search in the swagger, there is nothing called uptimesla, even not a thing named sla.

I will take some time to contact the azure cli guys for more information about this. I suspect that this feature may have been released, but not in this name.

It looks like the sku tier in request body is the key to flag it is a SLA cluster, i.e:

"sku": {
"name": "Basic",
"tier": "Paid"
}

See if this helps @ArcturusZhang, my debug logs:

"azure-cli": "2.5.1"
az aks create --resource-group myResourceGroup --name SLACluster --uptime-sla --node-count 1 --enable-addons monitoring --generate-ssh-keys --debug

Hi @yannart thanks for the effort!

Then we have already implemented this, see here and the comment:

Possible values include: 'Paid', 'Free'

I will then close this issue since this should be resolved, hope you do not mind. Please feel free to reopen if you have other questions or concerns
