Add rule to handle removal of a replicated cache filestore

Burak,

This rule is necessary to handle removal of the file-store from a replicated cache.
ie:

```json
{
  "infinispan" => {
	"cache-container"=> { 
		"web" => {
		"replicated-cache" => {
			"repl" => {
        		"file-store" => {
				"FILE_STORE" => "deleted",
			}
		}
	}}
	}}
}
```
