Remove the `logger` container from the logging daemonset. Remove the outgoing call from the poolmgr to the logger. Use Fluentd's Kubernetes filter to add function name and UID to influx metadata. This means fluentd now figures out when to start collecting function logs on its own, without being informed by poolmgr. This is great for other execution strategies, and for autoscaling, where fission isn't in direct control of function pod creation. Also adds an integration test to make sure logging keeps working.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
$ helm install --name my-release --set image=custom/fission-bundle,imageTag=v1 fission-all
If you're using minikube, set serviceType to NodePort:
$ helm install --name my-release --set serviceType=NodePort fission-all
You can also set parameters with a yaml file (see values.yaml for what it should look like):
$ helm install --name my-release -f values.yaml fission-all
