[JBoss JIRA] (ISPN-5600) Optimize transactions on multiple caches

> NON_XA transactions that span multiple caches are registered as multiple synchronizations, and these synchronizations are often processed sequentially ^1^; therefore, we send synchronous PrepareCommand for each cache and then CommitCommand for each cache as well, delaying the commit by these round-trips.
> Since the targets for different caches may differ, we still need to send the RPCs separately, but in parallel. Therefore, there should be one uber-synchronization for all caches that use NON_XA mode (and maybe something similar with XA). I believe that using single synchronization could save some allocations, too.
> ^1^ Not sure if full-fledged JTA implementations do that; JTA spec does not say anything about the order of synchronizations and whether these should be processed in parallel.

> The AsyncCacheWriter modification queue is not sent with state transfer when the store is shared. A joiner can then read from the shared store a stale version of entries that have updates in the modification queue but are no longer in memory (because they were either removed explicitly, or evicted).

[JBoss JIRA] (ISPN-5574) Define high-level cache capabilities

> Infinispan's configuration is very flexible, and it's sometimes hard to figure out how different settings affect things like cache consistency.
> For example, the lucene-directory module uses the fairly complicated {{Configurations.noDataLossOnJoiner()}} method to validate that a cache is safe for storing lucene indexes.
> Another example is users who would like to use a store for backup, but they don't want read from the store for M/R tasks or when get(k) doesn't find the key in memory.
> One idea would be to define a set of "capabilities" like "state-transfer-complete" or "all-data-in-memory". The user could then add those capabilities in the cache definition, and the cache won't start if the configuration violates those capabilities. The capabilities would also be used internally, to improve the error message when a feature requires a particular combination of settings.

[JBoss JIRA] (ISPN-5572) Exposed JMX MBeans should be separate components

> We currently expose internal components as JMX MBeans, and that makes our JMX "API" very unstructured. The exposed MBeans should be separate components, and the only concern in their interfaces should be ease of use.
> One example of JMX getting in the way of refactoring is {{CacheMgmtInterceptor}}. The interceptor chain is dynamic, so it should be possible to insert the interceptor only when statistics are enabled. But because the {{statisticsEnabled}} attribute is on the interceptor itself, that becomes a lot trickier, and we had to introduce a separate configuration attribute that disables statistics permanently (ISPN-5542).
