Stop creating useless network stacks for primary-replica

When network resources are NOT provided via the setup.env file then a
new VPC is created with its related components, such as subnets and IGW.

However, when network resources ARE provided externally via the
setup.env file, then the network stack doesn't do much except returning
the provided input values as output, for other stacks to consume.

This causes the creation of an empty stack, with no resources created,
but just outputs.

Prevent the creation of empty network stacks by checking the existence
of VPC related input parameters and skip the creation of the stack, when
they are defined.
