Improve Cache Stores configuration screen

Infinispan administrators should be able to select and configure any cache store easily, without having to enter class names and other free-form properties.

Only one tab ‘Cache store’ will be displayed in the cache configuration options
The user will have the option to select a type of store from the list (Single File, LevelDB, …) + the option ‘NONE’

When the option is changed, all the generic + specific properties will be shown below.
Properties should be presented as combos, if they are enumerable. For example, class (if there’s a way of filtering all implementing classes in classpath).
Sensible defaults should be set.
