Vincent Ambo 03bfe08e1d chore: Significantly restructure folder layout
This moves the various projects from "type-based" folders (such as
"services" or "tools") into more appropriate semantic folders (such as
"nix", "ops" or "web").

Deprecated projects (nixcon-demo & gotest) which only existed for
testing/demonstration purposes have been removed.

(Note: *all* builds are broken with this commit)

# This tool mimics a subset of the interface of 'pass', but uses
# Google Cloud KMS for encryption.
#
# It is intended to be compatible with how 'kontemplate' invokes
# 'pass.'
#
# Only the 'show' and 'insert' commands are supported.
