Support reusing credentials from azure/login action

[Rhuan Barreto]

Is your feature request related to a problem? Please describe.

I'm trying to use the SWA CLI in order to have more control over the the build and deployment of multiple environments in GitHub. So I'm not using the GitHub action. I normally use the federated login from Github in order to perform tasks in workflows and the azure/login action. Doing this, I don't need to setup client secrets. But this fails:

... Build steps ...
- name: Azure login
  uses: azure/login@v1
  with:
    client-id: ${{ vars.APP_CLIENT_ID }}
    tenant-id: ${{ vars.APP_TENANT_ID }}
    allow-no-subscriptions: true
- name: Deploy
  run: |
    npm i -g @azure/static-web-apps-cli
    swa deploy --no-use-keychain --config-name ${{matrix.environment}} --env Production

It gets stuck trying to open a browser and wait for a device code login. SWA CLI only accepts client secrets as an identity.

Describe the solution you'd like

I wanted the SWA CLI to reuse the credentials already set in the azure/login action so it doesn't need to use client secrets.

Describe alternatives you've considered

So far only alternative today is to use client secrets
