lstk az Azure CLI proxy

[carole-lavillonniere]

Motivation

Bring Azure CLI integration into lstk so users can run az commands against the LocalStack Azure emulator. Uses the wrap model (isolated AZURE_CONFIG_DIR), not start-interception global mutation — it mirrors lstk aws and leaves the user's global ~/.azure untouched.

Depends on #262 (Support starting the Azure emulator) to actually launch the emulator via lstk start.

Approach

The Azure CLI has no --endpoint-url/--profile; the only isolation knob is AZURE_CONFIG_DIR. Inside that isolated dir we register a custom Azure cloud (LocalStack) whose endpoints point at the LocalStack Azure emulator, activate it, disable instance discovery, and perform a one-time dummy service-principal login:

• lstk setup azure runs (against the isolated AZURE_CONFIG_DIR):
  • az cloud register|update --name LocalStack --cloud-config '{…}'
  • az cloud set --name LocalStack
  • az config set core.instance_discovery=false
  • az login --service-principal -u any-app -p any-pass --tenant anytenant
• lstk az <args> runs az <args> with just AZURE_CONFIG_DIR set — no HTTP(S) forward proxy. az talks directly to LocalStack for Azure service URLs and to the real internet for everything else (extension downloads, AAD static content, etc.).

Closes FLC-656

Awesome - thanks @carole-lavillonniere!

Note that I have not actually tested this out, but the Azure-specific parts LGTM 🙏

@bblommers Not sure if it's a known issue, but when trying az login, I get this error which believe it's on the emulator or az cli config:
