Moves to role recipe and updates kitchen tests

Adds a web recipe that serves the purpose of standing up a web
server.

This also cleans up the test kitchen config to use the default recipe
and allow for cloud based testing.
Spec test fixes and attribute based data_bag selection

This updates a number of things to get the chefspec tests passing and
sets it up to allow for the databag to be specified in an attribute.
