Create initial vip-config.php file

[kevinfodness]

Description

The configure script creates the vip-config folder, but not the vip-config.php file that belongs in it.

Use Case

When creating a project based off of this repo and selecting WordPress VIP as the target, the baseline vip-config.php file should be copied from VIP's skeleton.

Acceptance Criteria

• When running the configure script and specifying VIP as the target, copy the VIP Go Skeleton vip-config.php file into the newly created vip-config folder.
