[Feature Request] Support --force-refresh in az account get-access-token

[jiasli]

Requirement

There are some use cases where the user wants to get a new/fresh access token, bypassing the ADAL/MSAL token cache.

More info at Azure/azure-powershell#14005.

Proposed solution

Support --force-refresh in az account get-access-token.

Additional context

ADAL doesn’t support force_refresh:

    def acquire_token(self, resource, user_id, client_id):

MSAL supports force_refresh:

    def acquire_token_silent(
            self,
            scopes,  # type: List[str]
            account,  # type: Optional[Account]
            authority=None,  # See get_authorization_request_url()
            force_refresh=False,  # type: Optional[boolean]
            claims_challenge=None,
            **kwargs):

you can do the following as a temporary solution to re-generate the access token:
az account clear
re-login and then execute get-access-token again
