Extended the queries language to support bind variables which are bound in the execution stage, before creating a raft command. Adjusted `test_broadcast_tables.py` to prepare statements at the beginning of the test. Fixed a small bug in `strongly_consistent_modification_statement::check_access`. Closes #11525
