Feature/create cluster

[Tatsinnit]

This PR is to enable 2 things, which will be amazing for next level of AKS Developer Experience we could aim for. ❤️☕️

• Multi Step Wizard Mechanism.
• Minimalistic Create Standard AKS Cluster

Details: (Please also refer to screenshots below)

The Create Cluster will appear as a subscription level subMenu, the key thing about this feature drop is that this feature is short, needs least input form the user and all user need to add is the valid cluster name and in step-2 select the Predefined resource group name form the drop down.

With this experience we are enhancing the developer experience and now fully one-click functionality to create standard cluster with just 2 steps from VsCode.

User will right-click on their subscription in the tree note, select Create Standard Cluster --> which will initiate a 2 step wizard - Ste-1 : Will accept valid cluster name and Step-2 : Select Resrouce Group Name - as a location the location of the resource group name will be taken as the location of the cluster and all user need to do is now setback and let VsCode experience do its thing call the aks managed operation and in the end user gets served with message box with click -> nav to the portal cluster page which will take user to the exact cluster which is created.

Thanks all, @peterbom , @rzhang628 , @qpetraroia and fyi : @gambtho ❤️☕️ 🎊
