Move 'standard' profile projects into Islandora-Devops

[alxp]

The islandora-playbook project, specifically the changes currently living in the "install_profile" branch, now lets a user specify a particular composer project and install profile in their Vagrant variables.

A user can run the playbook to install either 'islandora_install_profile_demo" - the in-progress work to build a more complete install profile, or "islandora_profile" - the modules originally downloaded and enabled when running the playbook.

This project now relies on two composer projects:

https://github.com/roblib/islandora-project

A bare-bones top-level composer project that sets up the repositories and directory structure for a generic Drupal project.

https://github.com/roblib/islandora_profile

This is the Islandora Standard profile, which sets up a site running islandora and islandora_defaults.

These two repositories should be moved in to Islandora-Devops, with appropriate changes made to the composer project name.
