is started to fail after this PR merge. Could you please check if it is related?

Why should this high-level functionality pollute Semaphore API? Resource 
acquisition control is not an only semaphore use case. To my mind, it's better 
to put this method to some utility class like IgniteUtils.

In order to support async actions (as per ticket description) the method 
signature should be 

{code}
 IgniteFuture acquireAndExecute(Callable action, int 
numPermits);
{code}

Such signature makes the contract explicit, and more importantly it correctly 
unwraps the input future to return the type T and not {{IgniteFuture}} as 
would be the case with the original signature.
