Pluggable storages

[SanderMertens]

Describe the problem you are trying to solve.
There are scenarios in which using a table-based storage has usability and/or performance issues:

• when stable pointers are required
• when a component would introduce lots of fragmentation
• when it is expensive to move
• when there are a lot of components to move

Describe the solution you'd like
An interface that makes it possible to use custom storage plugins which can be configured per component.
