[Bug report] az devops invoke should support --url parameter

**Is your feature request related to a problem? Please describe.**
Current implementation of `az devops invoke` fetches information from`GET /{organisation}/_apis/ResourceAreas`. Some resource areas are missing from the endpoint and they cannot be used with `az devops` invoke command. Missing e.g.
* /{organization}/_apis/securityroles/scopes/{scopeId}/roleassignments/resources/{resourceId} that is required to set role assignments for objects

**Describe the solution you'd like**
Allow passing full URL to CLI without using information fetched from `GET /{organisation}/_apis/ResourceAreas` and `OPTIONS /{organisation}/_apis?allHostTypes=True` at all

Alternative solution is to work with ADO API owners and add all missing resource area definitions

**Additional context**
Running `az devops invoke --debug --org https://dev.azure.com/xxxx/ --area securityroles --resource scopes --http-method GET` fails with
```
