Fix: Serverspec v2 spec helper
Add: Tests for SSL vhost / cert generation

We want the LWRP to have responsibility for dropping off certs and
creating the correct SSL config for a vhost.
Add: Chefspec tests for SSL cert/vhost
Add: Testapp SSL cert and updated resource usage

It turns out that there are cases when we might want to create
but not enable, or disable but not delete a vhost.  This test
cookbook uses some of these actions.

The default vhost needs to be removed because it contains an SSL
directive that conflicts with the one our LWRP generates.
