There is a bug in how pyangbind translates yang models into python bindings. The model always sets integer values to 0 by default, so there is no way to check if a user has provided a value that is equal to 0. This is problematic for ICMP and VLAN (among others) because 0 is a valid input value.
This change converts ICMP and VLAN fields to union types so that acl-loader will treat them as null values unless a user explicitly adds an integer value.

Python 3 is more strict with `__slots__`. As per the [documentation](https://docs.python.org/3/reference/datamodel.html#notes-on-using-slots):
> \_\_slots\_\_ are implemented at the class level by creating descriptors (Implementing Descriptors) for each variable name. As a result, class attributes cannot be used to set default values for instance variables defined by \_\_slots\_\_; otherwise, the class attribute would overwrite the descriptor assignment.
This was apparently missed when making sonic-config-engine compliant with Python 3, and errors like the following would be seen:
```
tests/acl_loader_test.py:10: in <module>
from acl_loader.main import *
acl_loader/main.py:8: in <module>
import openconfig_acl
/usr/local/lib/python3.7/dist-packages/openconfig_acl.py:24: in <module>
class yc_state_openconfig_acl__acl_state(PybindBase):
E ValueError: '_pybind_generated_by' in __slots__ conflicts with class variable
```
