Add a jsonnet library for help with building templates

as a templates builder, I would like a reusable jsonnet library filled with functions that make it simple to create resources or assets in influxdb.

This would be similar to this library from grafana: https://github.com/grafana/jsonnet-libs/blob/master/grafana-builder/grafana.libsonnet

Start by reviewing the referenced Grafana jsonnet library to understand the intended structure and scope. Define which InfluxDB resources or assets the reusable library should cover and how its functions should be used. Done means a reusable library exists that simplifies building those templates.
