Bug 561777 - [Passage] [Spring] design a way to declare licensing requirements

[ruspl-afed]

Migrated from https://bugs.eclipse.org/bugs/show_bug.cgi?id=561777

Have a lokk at the API revision work done in 561380 regarding licensing requirements resolution. Here ResolvedRequirements service is invited to encapsulate a way a developer can declare a licensing requirement (Requirement).

Eclipse product developer can use either BundleRequirements or ComponentRequirements implementations, which are both equinox-dependent.

And there are no universal, flatform-agnostic implementation (can appear though).

For a Spring-app developer employing Passage Spring framework definitely can provide it's own way(s) to register licensing requirement.

In the scope of this task this/these should be designed and implemented, add subtasks if necessary.
