Use UUID_TO_BIN() and BIN_TO_UUID() in MySQL

[skalee]

Binaries in database logs are difficult to read. When working with MySQL backend, we should consider replacing explicit binaries with UUID_TO_BIN('human-readable-uuid')andBIN_TO_UUID` function calls.

See:

• https://mysqlserverteam.com/mysql-8-0-uuid-support/
• https://dev.mysql.com/doc/refman/8.0/en/miscellaneous-functions.html#function_uuid-to-bin
• https://dev.mysql.com/doc/refman/8.0/en/miscellaneous-functions.html#function_bin-to-uuid

Unfortunately, MariaDB does not provide such functions yet. See:
