Version Branch: support/1.2.x Found on image hyperledger/iroha:latest by iroha-python library user.

Detail description: After closing a connection for block stream the thread created for this connection is not closed.

Script for reproducing: block_getter.py.zip

Actual result: Memory consumption increases with each connection created. log file: iroha.log

@stepanLav, in addition to this bug, I noticed that each time that a transaction is performed thru the python client, the iroha memory increases but never goes down. Is it expected?
