---------------------------------------------
May be Later I will look at our lock implementations. Right now I wrote
benchmark IgniteCache.lock(...) vs Ignite.reentrantLock(...). There are results:
//Ignite.reentrantLock(...)
Benchmark (create) (failoverSafe) (fair) Mode
Cnt Score Error Units
JmhCacheLocksBenchmark.testIgniteLocks true true true thrpt
10 873,775 ± 60,388 ops/s
JmhCacheLocksBenchmark.testIgniteLocks true true false thrpt
10 1177,804 ± 162,082 ops/s
JmhCacheLocksBenchmark.testIgniteLocks true false true thrpt

Looks like IgniteCache.lock(...) faster than Ignite.reentrantLock(...) at ~8
times.
I will investigate the reason.
> Ignite.reentrantLock looks much slower than IgniteCache.lock.
