MDEV-6676: Optimistic parallel replication
Implement a new mode for parallel replication. In this mode, all transactions are optimistically attempted applied in parallel. In case of conflicts, the offending transaction is rolled back and retried later non-parallel. This is an early-release patch to facilitate testing, more changes to user interface / options will be expected. The new mode is not enabled by default.
