Description

Consider the following pseudo-code:

        IgniteTransactions transactions = ignite1.transactions();
        Transaction tx = startTransaction(transactions);
        cache.put("key1", 1);
        tx.stop();

And in another thread:

                transactions.txStart(tx);
                cache.put("key3", 3);
                cache.remove("key2");
                tx.commit();

The Api should be implemented , that let you continue transaction in another thread.
method suspend() should mark the transaction as unavailable for further commit.
method resume should resume the transaction.

reason behind the proposal :
Consider the next scenario:
we begin transaction, doing some changes and start async future that will be able to introduce futher changes into transaction and commit it in the end.
