Can a user get the two yaml file without cloning this entire openj9-utils repo?
We need some documentation on how to change the Java version for JITServer. Moreover, what happens if a user needs to have a JITServer with Java8 and a JITServer with Java11? We need two different JITServer deployments.

Could you please add license information much like the helm files have?

LGTM. One I have is about the particle 'sample' in the name of the JITServer service/deployment/pod. E.g. service/openj9jitserverchart-sample-openj9-jitserver-chart
How is the name being constructed?
I also feel there is a bit of redundancy between "openj9jitserverchart" and "openj9-jitserver-chart"

In service.yaml from the jitserver helm chart templates, name is defined as name: {{ include "openj9-jitserver-chart.fullname" . }} which translates to release-name-chart-name.

release-name is defined here in the file included in this PR as openj9jitserverchart-sample and chart-name comes from chart.yaml file in the jitserver helm chart where its value is openj9-jitserver-chart.

Thus, the name translates to openj9jitserverchart-sample-openj9-jitserver-chart.

The release-name can be changed to openj9jitserver and name in service.yaml from the jitserver helm chart templates can be changed to {{ .Release.Name }}-service which would then translate to openj9jitserver-service. The same thing could then happen for deployment template as {{ .Release.Name }}-deployment.
