autoload functions

[MenkeTechnologies]

dkme, dkmd functions are defined in docker-aliases.plugin.zsh. This slows down startup and increases memory overhead. They should be in a dir in fpath and autoloaded so they are only defined when used. The plugin file should put this dir in fpath and autoload all the function files. This is zsh best practice.

This plugin adds to fpath and autoloads the plugin functions.
