remove code duplication from HotRodOperationsImpl

HotRodOperationsImpl - contain code duplication in the way retry is handled. Basically following logic is replicated through all operations:
Transport transport = getTransport(key, true);
int retryCount = 0;
do {
try

{ //to something here }

catch (TransportException te)

{ logErrorAndThrowExceptionIfNeeded(retryCount, te); }

finally

{ releaseTransport(transport); }

if (shouldRetry(retryCount))

{ transport = getTransport(key, false); }

retryCount++;
} while (shouldRetry(retryCount));
throw new IllegalStateException("We should not reach here!");

This should be factorized in a TemplateMethod because: a - duplication is evil and b - duplication is more even in a reference implementation.
