set innodb_file_per_table to ON for MySQL / Galera
InnoDB uses a single file by default which can grow to be
tens/hundreds of gigabytes, and is not shrinkable even
if data is deleted from the database.
Best practices are that innodb_file_per_table is set to ON
which instead stores each database table in its own file, each of
which is also shrinkable by the InnoDB engine.
Closes-Bug: #1660722
