appservice: show/list command doesn't get linux typed webapps or functionapps

[yugangw-msft]

With new app types added for linux like app,linux and functionapp,linux, the get/list command gets out of sync, because it still filter using old types of app and functionapp

This local validation code is blocking Azure Web Apps for Containers from being listed or shown:

FUNCTION_APP_TYPES = ['functionapp', 'functionapp,linux']
WEB_APP_TYPES = ['app', 'app,linux']

def validate_existing_function_app(cmd, namespace):
    _validate_existing_app(cmd.cli_ctx, namespace, FUNCTION_APP_TYPES)

def validate_existing_web_app(cmd, namespace):
    _validate_existing_app(cmd.cli_ctx, namespace, WEB_APP_TYPES)

def _validate_existing_app(cli_ctx, namespace, app_type):
    client = web_client_factory(cli_ctx)
    instance = client.web_apps.get(namespace.resource_group_name, namespace.name)
    if instance.kind not in app_type:  # pylint: disable=no-member
        raise CLIError('Usage Error: {} is not a correct app type'.format(namespace.name))
    setattr(namespace, 'app_instance', instance)

The kind for Web Apps for Containers is 'app,linux,container'. Any new web app types, e.g., web apps for containers and Azure Functions Containers, will appear "broken" from a CLI end user perspective until this array is updated to include the correct kind values. Users will receive the 'Usage Error: {} is not a correct app type' message for (at least) webapp list and webapp show if their webapp is container based. Is there a more dynamic way to perform this client side validation? Is this client side validation necessary?

@josalem, I will remove the client logics considering the webapp back-end service is continuously changing w/o notifications // cc: @ahmedelnably @panchagnula

The change was in. You can verify through docker: docker run -v ${HOME}:/root -it azuresdk/azure-cli-python:dev

Verified fixed via prompt.ws for #5335 .
