fix Issue #588 add prefix for metrics exposed by Prometheus

What was changed

added server.metrics.prefix to values.yaml

Why?

per feature request, and the prefix is helpful for complex installations

1. closes 588
2. How was this tested:
   added configuration setting to values.yaml and ran helm template and ensured that the correct setting made its way to the proper section in the config map file.
3. Any docs updates needed?
   I don't think so, as the other settings are not in the readme.

Thanks for adding this! We need this as well :)

Just a heads up, I noticed the contribution guide says:
"Note: Please do not bump the Chart version as this is automated as part of our release process."

[robaho]

@raymondregrello but the docs in the Chart.yaml state you should update it

helm-charts/charts/temporal/Chart.yaml

Line 40 in 81cc46d

# This is the chart version. This version number should be incremented each time you make changes
