    IGNITE-3678: Test for partition distribution

    This submission includes a test that will assert the even and safe distribution of partitions when server nodes are forcibly killed.
    
    Additionally, the following are included:
    
    (1) A new `Assertion` interface. This looks similar on the surface to `IgnitePredicate` - however there are two subtle differences:
    - it returns `void`, not `boolean`
    - it throws `AssertionError`
    Since this does not return `boolean`, the caller does not have to check for the result of the assertion; if the assertion fails an exception is thrown which contains the details of the failed assertion.
    
    (2) `GridRollingRestartAbstractTest`: a new abstract test class that is extended for tests that require:
    - multiple JVMs
    - the first JVM to be a client (i.e. not own any partitions)
    - the server JVMs to be killed forcibly (not gracefully) while the test executes

    This submission includes a test that will assert the even and safe
    distribution of partitions when server nodes are forcibly killed.
    
    Additionally, the following are included:
    
    1. A new Assertion interface. This looks similar on the surface
       to IgnitePredicate - however there are two subtle differences:

       Since this does not return boolean, the caller does not have
       to check for the result of the assertion; if the assertion fails
       an exception is thrown which contains the details of the failed
       assertion.

> Create a test that will assert the following conditions in a running cluster while server nodes are (forcibly) killed and restarted:
> * even distribution of partitions 
> * safe distribution of partitions (where data will not be lost if a single node is killed) - this means the cache is configured with a backup count >= 1 and partitions are backed up to a different node from the primary
