1. (t) replication spawn error rockstor#2766 …

   Update replication code re Py2.7 to Py3.11.
   - Modernise previously missed replication imports re Py3.*
   - Force bytes format for replication messages and commands.
   Zmq requires bytes format.
   - Minor modification re Pythnon 3 behaviour re dict.keys(),
   we previously relied on an implicit Python 2 behaviour.
   - Move to Fstrings for all issue focused files.
   - Parameter/return type hinting.
   - Removed an unused local variable.
   - black format update
   - Improve error diagnostic content of receiver failing to
   retrieve senders IP address from sent appliance ID.
   - Improve debug logging.
   - Remove receiver 'latest_snap or b""' argument to improve
   readability.
   - reduce retry iterations from 10 to 3.
   - Remove use of None from within zmq command/message passing:
   to help with stricter type hinting.
   - remove libzmq socker.set_hwm.
   - refactor poll -> poller socks -> events for readability.
   - additional explanatory comments re sockets etc.
   - Enable tracker on listender_broker, sender, and receiver's
   response: improves robustness, and aids in debugging.
   - add zmq_version and libzmq_version properties to sender and
   receiver.
   - adapt iostream behaviour: this differs between Py2.7 & Py3.*.
   - Fix existing bug re very low send byte count.
   - harmonize on btrfs binary location to fs.btrfs for replication.
   - readability refactoring improvements.
   - keep receiver self.share/snap naming as str, encode before
   send only.
   - Avoid logging btrfs data stream contents.
   - Set read1() bytes read to 100MB max.
