Why I did it
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.
Because 201911 is still using python2, we need a separate PR from #6932.
How I did it
Generated the bindings for python2.
How to verify it
Run sonic-mgmt tests to verify existing acl behavior is intact. See also new tests in sonic-net/sonic-utilities#1469.
