feat templater: Add 'pass' lookup function
This introduces support for looking up secret values in the 'pass' command line
tool (https://www.passwordstore.org/).

Values like passwords can be interpolated from pass and even more complex
structures like certificates for Kubernetes Secrets can be retrieved and base64-
encoded as necessary.

Fixes #2
