primary-replica: separate HTTP from SSH traffic

Using a Network Load Balancer forces all the traffic to be handled at
the transport level (Level 4). Whilst this is fine for SSH traffic, it
is not ideal for HTTP traffic, which should be handled at application
level (Level 7).

Split HTTP and SSH traffic and handle HTTP traffic via an Application
Load Balancer.

This unlocks many benefits, among which:
- Advanced routing: based on path, host, headers, request method,
  source IP, etc
- Application-based sticky sessions
- Seamless integration with X-Ray
- Detailed access logs
