cloudstack 4.x -- enable security groups and vlan support.

[Shashi Dahal]

Hi All,

We have 2.2.14 with advance zone ( for VLANs ) with security groups, which I do 
not see it possible to do it in CloudStack 4.x anymore.
If someone knows how to make this possible, can you please provide some hints 
on how to achieve this.

Cheers,
