Cleaner per-service and routing config

[gouthamve-but-enterprise]

Right now there are two places where the route matching config exists:

One is on a per-service level:

discovery:
  services:
    - namespace: multi-k
      name: java-serv
      open_ports: 8085
      routes:
        incoming:
          - /greeting123/{something}
        outgoing:
          - /*

And another is on a global level:

routes:
  patterns:
    - /basic/:rnd
  unmatched: path
  ignored_patterns:
    - /metrics
  ignore_mode: traces

We need to reconcile the two. For example, I think ignore_patterns and unmatched are useful in the per-service level as well. And that incoming / outgoing differentiation is useful on a global level as well.

Also the two being in completely different places is weird as well.
