> Implement IgniteReentrantLock data structure
> --------------------------------------------
>                 Key: IGNITE-642
>                 URL: https://issues.apache.org/jira/browse/IGNITE-642
>             Project: Ignite
>          Issue Type: Sub-task
>          Components: data structures

> We need to add {{IgniteReentrantLock}} data structure in addition to other data structures
provided by Ignite. {{IgniteReentrantLock}} should have similar API to {{java.util.concurrent.locks.ReentrantLock}}
class in JDK.
> As an example, you can see how [IgniteCountDownLatch|https://github.com/apache/incubator-ignite/blob/master/modules/core/src/main/java/org/apache/ignite/IgniteCountDownLatch.java]
is implemented in [GridCacheCountDownLatchImpl|https://github.com/apache/incubator-ignite/blob/master/modules/core/src/main/java/org/apache/ignite/internal/processors/datastructures/GridCacheCountDownLatchImpl.java]
> In general we need to have an entity in ATOMIC cache storing lock-owner identifier together
with a queue of waiters.
