A template function has been added that allows one to template the
Git hash of the surrounding repo. This is useful to be able to inspect the
deployment revision of an object in Kubernetes.
This is actually several refactors in one:
* rename "fileContent" function to "insertFile"
* pass the resource set path to the "insetFile" function
* update docs and example with a pipeline including indentation
adjustments for the inserted file
Adds a 'fileContent' template function to insert the literal contents
of a file specified in the template.

Adds documentation for `if` and `range` statements in Go templates
and also more explicitly points people at the Go documentation for
more information.
