https://github.com/apache/ignite/pull/952 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

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:
(a) it returns void, not boolean
(b) 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:
(a) multiple JVMs
(b) the first JVM to be a client (i.e. not own any partitions)
(c) the server JVMs to be killed forcibly (not gracefully)
while the test executes
