Dave Eargle 72dc282aa0 ub1404 dev workflow
Tweaks to the recipes to avoid repetition of work, and ub1404 dev,
* let apt cookbook handle apt-update globally
* do not download, configure, make, make install if the package is
already installed
* add guards for file deletion to first check whether file is present
* use docker cookbook for image building and running, to only build if
not alrady built and only run if not already running
* drop mysql table and recreate each time

Also,
* bump Docker cookbook to 4.9.3
* bump mysql cookbook to 8.5.1
* add apt cookbook for better apt-update management
* bump depends versions and add apt
* modify readme with customization instructions
* modify all chef runlists to call apt first in the runlist
* add a vagrantfile for dev of ub1404
