Add Starter Plugins

[valendesigns]

• Customize Posts
• Customize Snapshots
• Customize Object Selector
• Query Monitor
• WP Redis
• REST API?
• S3?
• Jetpack?
• TBD...

Plugins should be managed via Composer which means they either need to be on packagist or if they are internal and on Github we might need to update their package.json files to be compatible.
