feat: (IAC-897) Annotate NGINX to indicate the desired subnets to provision LBs internal IP addrs from #526
Add documentation for the added AWS specific configuration variable V4_CFG_AWS_LB_SUBNETS
The V4_CFG_AWS_LB_SUBNETS values specifies the AWS subnets and by association the AWS availability zones to deploy the load balancing service to. Specifying a subnet value or values for this variable supercedes the Subnet Discovery method decribed in AWS docs and eliminates the need to tag subnets as described in scenario 2 of this table

AWS NLB shows AZ was set to us-west-1a and it's private IP address is assigned from CIDR 192.168.130.32/28 which is the CIDR for subnet-033f8eaf7b0c8a744
AWS NLB shows AZs set to us-west-1a and us-west-1c and it's private IP address is assigned from CIDR 192.168.130.32/28 and CIDR 192.168.130.48/28 which are the CIDRs for subnet-033f8eaf7b0c8a744 and subnet-0c20ecd67feefbee7 respectively
