terraform import doesn't support runAzLogin: true

[dvasdekis]

Describe the bug
Running import without runAzLogin: true I get:

 Error: Error building AzureRM Client: obtain subscription(*azure sub id*) from Azure CLI: Error parsing json result from the Azure CLI: Error waiting for the Azure CLI: exit status 1: ERROR: Please run 'az login' to setup account.

But running import with runAzLogin: true I get the same error.

To Reproduce
Try the below pipeline:

trigger:
- master
pool:
  vmImage: windows-latest
parameters:
- name: 'environments'
  type: object
  default: 
  - dev
  - tst
  - prd

steps:
- ${{ each env in parameters.environments }}:
  - task: TerraformInstaller@0
    displayName: install terraform
  - task: TerraformCLI@0
    displayName: 'Terraform set workspace to ${{ env }}'
    inputs:
      workingDirectory: $(Build.SourcesDirectory)/infra
      command: workspace
      workspaceSubCommand: new
      workspaceName: ${{ env }}
  - task: TerraformCLI@0
    displayName: 'terraform init ${{ env }}'
    inputs:
      workingDirectory: $(Build.SourcesDirectory)/infra
      command: init
      backendType: local
  - task: TerraformCLI@0
    displayName: 'terraform import ${{ env }}'
    inputs:
      command: import
      workingDirectory: $(Build.SourcesDirectory)/infra
      resourceAddress: azurerm_resource_group.myrg
      resourceId: "/subscriptions/*redacted*/resourceGroups/myrg"
      runAzLogin: true

Expected behavior
I want to be able to import my resource groups, like I can on desktop.

Agent Configuration
All default versions, Azure hosted

@dvasdekis, in order to use runAzLogin, you will need to specify a service connection via the environmentServiceName input in order for the azure cli to authenticate. The task uses the service connection's credentials to run az login. Without specifying the service connection, then it would have no means to authenticate against azure.
When doing this on your desktop, you have likely already logged into the az cli before running terraform import. Terraform will automatically pick the az cli context up to authenticate against azure.
If you cannot use a service connection, an alternative is to set the environment variables terraform expects for the azurerm provider. The task provides a means to more easily establish these via Secure Var Files. If you specify a secure var file via secureVarsFile input whose extension ends with .env it will export the vars set in the .env file as environment variables on the agent.

Thanks Charles! Setting the service connection worked a treat :)
