Vincent Ambo bcd7710be5 feat(tools): Introduce pass-compatible wrapper using Cloud KMS
Adds a shell script that supports a subset of the 'pass' interface for
compatibility with kontemplate, and wraps kontemplate in a script that
places this version on the PATH.

This makes it possible to use Cloud KMS encrypted secrets with kontemplate.
