feat(templater): Add insertTemplate function
Similar to insertFile, but runs the templating against the file before
inserting.

This is useful for sharing common config between yaml files, e.g. volume
mounts in a deployment.yaml and cronjob.yaml, and it's useful to be able
to use the `configHash` annotation pattern with a templated
configmap.yaml
