Move distributed transaction engine logic Summary: This change introduces a pure virtual initial implementation of the transaction engine which is then implemented in two versions: single node and distributed. The interface classes now have the following hierarchy: ``` Engine (pure interface) \| +----+---------- EngineDistributed (common logic) \| \| EngineSingleNode +-------+--------+ \| \| EngineMaster EngineWorker ``` In addition to this layout the `EngineMaster` uses `EngineSingleNode` as its underlying storage engine and only changes the necessary functions to make them work with the `EngineWorker`. After this change I recommend that you delete the following leftover files: ``` rm src/distributed/transactional_cache_cleaner_rpc_messages.* rm src/transactions/common.* rm src/transactions/engine_rpc_messages.* ``` Reviewers: teon.banek, msantl, buda Reviewed By: teon.banek Subscribers: pullbot Differential Revision: https://phabricator.memgraph.io/D1589 2018-09-05 02:30:58 +08:00			`/// @file`
