Machine Agent Service Points to Port 80 Internally

[stemjacobs]

The default configuration of the most recent machine-agent-analytics container at:
docker.io/appdynamics/machine-agent-analytics

Listens on port 9090 by default per its configuration.

Values available for these helm charts include an analytics.port value (which is also set to 9090 in the default values file):
https://github.com/Appdynamics/appdynamics-charts/blob/8616f2fffcfa6128a731eaaf0dc9f9875ef945f9/machine-agent/values.yaml#L68

The targetPort in the current service is set to http:
https://github.com/Appdynamics/appdynamics-charts/blob/8616f2fffcfa6128a731eaaf0dc9f9875ef945f9/machine-agent/templates/service.yaml#L13

This results in a revoked connection since nothing is listening on port 80 with the indicated machine-agent-analytics container.

( Note: To first establish a connection to the machine agent containers with this service, the selector must also be corrected as indicated in issue #16 )

Changing the targetPort to 9090 resolves the issue.
