Add initial minion configurations for WSUWP Indie

This copies the current config from WSUWP, but drops the MySQL settings as I'm not entirely sure that they're necessary here. We'll find out soon and update accordingly.
Add a state file for WSUWP Indie Dev to process project pillar data

This allows us to bring over project specific data from an individual wSUWP Indie development configuration
Match the correct pillar directory for the WSUWP Indie development environment
Load pillar data from mounted /vagrant directory in WSUWP Indie development
Remove (currently) unnecessary host management in state file

The method we use here isn't lovely, Salt allows for something much better.

We also take advantage of vagrant-hosts to do this for us inside the guest machine, so this line is not needed.

In the future, it could be smart to handle host management with Salt in a different fashion.
Prefix states to avoid conflicts with other sls files
MySQL info is necessary for the Vagrant config
Consolidate service flushing to one command

The cmd.run ID conflict was still present with unique prefixes. I think there may be something around the use of cmd.run twice in the same state assertion.

This is currently working, committing for an official test.
Require the webserver sls before copying nginx configs
Temporarily comment out wp-cli installation for WSUWP Indie

This slows down the provisioning a bunch. It may be necessary, but we should see what we can do to speed things up.
Uncomment wp-cli state for development

We'll need to explore some ways of speeding the install process for wp-cli up in the future. The biggest hang seems to be around updating the composer dependencies (I think).
