Deprecate the SharedBundle bundle

[netsensei]

Detailed description

The SharedBundle bundle contains a lot of "general" code which is called in the other bundles such as traits, templates, functions. It also contains the DefaultController which has the Dashboard action. And finally, it has the app:setup command and a few fixtures.

Context

The Bundle itself doesn't serve a real purposes. It's just something other bundles depend upon. As such, it violates the Single Responsibility Principle. Deprecating the module would vastly improve maintainability and testability of code.

Possible implementation

Breaks down in these tasks:

• Remove SharedBundle\Helper\SerializationHelper
• Move EnvironmentSpecificDataFixture to UserBundle & OAuthBundle
• Move DefaultController to DashboardBundle
• Deprecate Traits and integrate them in bundles
• Move Resources\views to App\Templates
• Move views to App\templates (or Assets?)
