feat: Docker Traefik routing based on host header (#1921)

## Description:
Docker Traefik is currently configured to route traffic based on three
custom headers: enclave short uuid, service short uuid and port number.
This type of routing rule is not possible with the K8S Ingress provider
so we are switching to use the single Host header instead with the
format: `<port number>-<service short uuid>-<enclave short uuid>`.

## Is this change user facing?
NO

## References (if applicable):
