`az functionapp config container set` is missing parameters that `az webapp config container set` has

**Describe the bug**
The `functionapp` subcommand is missing several key flags that the equivalent `webapp` command has.

This means when you deploy a Function App into Azure no functions appear.

Also as a side point, the fact that if `WEBSITES_ENABLE_APP_SERVICE_STORAGE` is missing or set to true, the Kudu runtime pulls the container but never uses it with NO logs is _so so so so_ confusing... 😖

To be quite honest the `az functionapp config container set` should default `WEBSITES_ENABLE_APP_SERVICE_STORAGE` to false as it's _pointless_ with it missing or on true as Kudu will just boot your app fine but never send requests to it... >.<;

**To Reproduce**
Try to deploy a new function with `az functionapp config container set` and the functions never appear if the variable isn't set to false.

**Expected behavior**
I should be able to supply `--enable-app-service-storage false` or better, hardcode it to false for this scenario as it should _never_ be true for a container.

**Additional context**


As you can see the webapp command has extra flags.
