Feature: Add support for BYOVPC deployments

[wombelix]

This PR add the necessary functionality that allows customers to use an already existing network setup, Bring Your Own VPC (BYOVPC). This will then also cover deployments on AWS Outposts Servers.

If at least at new Parameters VPCID, PublicSubnet1ID, PublicSubnet2ID, PrivateSubnet1ARouteTable, PrivateSubnet2ARouteTable, PublicSubnetRouteTable, PrivateSubnet1AID, PrivateSubnet2AID are set, the nested stack VPCStack will be skipped and the provided Parameters used instead.

We make the assumption that in case of a selection of 3 or 4 AZs the additional PrivateSubnet and RoutingTable ID(s) are also set. There is no additional logic to test it, if a Customer runs the stack without the appropriate and/or correct information, it will fail, which is fine.

Three new taskcat test profiles were added to cover the feature in the end-to-end tests. To achieve this, a new template test.byovpc.yaml is part of the PR, it contains the bare minimum to deploy the VPCStack and pass the Outputs as Parameters to the RHELHAStack (main.template.yaml). This simulates the behavior as if a Customer would deploy the stack into an already existing VPC.

Test deployment with all profiles defined in .taskcat.yml successful completed and verified.
