sjaakola 49791cbc6f 10.4-MDEV-27275 CREATE TABLE with FK not safe for PA
This commit contains a fix, where the replication write set for a CREATE TABLE
will contain, as certification keys, table names for all FK references.
With this, all DML for the FK parent tables will conflict with the CREATE TABLE
statement.

There is also new test galera.MDEV-27276 to verify the fix.
