Add Fusion/wave support in Azure compute environments

[drpatelh]

Pretty much the same issue as #311 but for Azure.

We have buttons in the UI now to toggle Fusion + Wave on but when you run the following commands for a Fusion enabled CE you don't see entries for waveEnabled or fusion2Enabled

$ tw compute-envs export --workspace=seqeralabs/showcase --name=seqera_azure_virginia                              

{
  "workDir" : "az://azure-benchmarking",
  "region" : "eastus",
  "forge" : {
    "vmType" : "Standard_E16d_v5",
    "vmCount" : 1,
    "autoScale" : true,
    "disposeOnDeletion" : true,
    "containerRegIds" : [ "4tcmOiDXXyYG40EIL4MIZq" ]
  },
  "deleteJobsOnCompletion" : "always",
  "deletePoolsOnCompletion" : false,
  "environment" : [ ],
  "discriminator" : "azure-batch"
}

$ tw compute-envs view --workspace=seqeralabs/showcase --name=seqera_azure_virginia
