Mismatch between README values.yaml and actual values.yaml

[lindhe]

The example for values.yaml in the README doesn't match the contents of the actual values.yaml. If the example from the README is up-to-date, I think those should be merged into the real values.yaml file (as comments, if they are not reasonable default values).

cluster-template-examples/README.md

It seems like rancherValues is unused, so that should be removed from the example.

This is resolved in #22.

[lindhe]

After #22, the example in README.md is almost identical to the contents of values.yaml. I think the examples should be removed from README.md, so we don't risk having out-of-date documentation again in the future.
