expose nodeport for logstash 5044

Issue-ID: OOM-819

Open the 5044 port on log/logstash as a nodeport for external log producers outside of the kubernetes cluster

https://wiki.onap.org/display/DW/LOG+Meeting+Minutes+2018-03-20

Q: on logstash port - see all-services.yaml in log pod - 5044
need to open officially on 30255 or in dev via adding (Logstash not externally available - no nodeport)
nodePort: {{ .Values.nodePortPrefix }}55

We already expose elasticsearch and kibana - just need to expose logstash
