ISPN-3106 Remove support for old (non-concurrent) distribution algorithm...

... for non-transactional clustered caches

* Deprecate LockingConfiguration.supportsConcurrentUpdates() and  LockingConfigurationBuilder.supportsConcurrentUpdates().
* Merge NonTxConcurrentDistributionInterceptor into NonTxDistributionInterceptor
* Remove tests for non-concurrent case

This is needed to simplify the interceptor before starting to fix it for the several out standing putForExternalRead related bugs.

Please integrate in master.
