Description

Ignite dumps diagnostic messages with pending objects in case of hanging,
but some information doesn't looks helpful:

Pending mvcc listener:
>>> o.a.i.i.processors.cache.mvcc.MvccQueryTrackerImpl$ListenerDecorator@261bd7b
>>> o.a.i.i.processors.cache.mvcc.MvccProcessorImpl$4@6f9e08d4

Let's fix toString methods for these objects to make message more informative.

Also, consider implementing IgniteDiagnosticAware by MVCC enlist futures.
