Add `exclude` option to `internal-services` in Spring integration

[ikhoon]

internal-service provides include options to opt in services to serve only in the non-service port. But exclude isn't supported to opt out of include. exclude option will be useful for less sensitive internal services. For example, in the case of the health check service, there will be a need to provide both the service port and the internal port because sensible information is not exposed by HealthCheckService if updating the status isn't supported in the API.

  ports:
    - port: 8080
      protocol: HTTP
  health-check-path: /...
  internal-services:
    exclude: HEALTH
    port: 9090

In addition to exclude, multiple internal service configurations would be helpful to respond to complex situations.

  internal-services:
    - include: DOCS
      port: 9090
    - include: HEALTH
      port: 9091
