Pre-aggregation queries are not GTID safe - MySQL

**Describe the bug**

Queries to create pre-agg tables use ` CREATE TABLE ... SELECT ` syntax.
This syntax is not valid when running MySQL with GTID based replication. [see here](https://dev.mysql.com/doc/refman/5.6/en/replication-gtids-restrictions.html)

GTID based replication also happens to be used by Google CloudSQL and is not configurable.
This means that pre-aggregations cannot by used.

Note: This issue theoretically will also appear when using statement based replication.

**To Reproduce**
[Run a MySQL database using GTIDs for replication](https://dev.mysql.com/doc/refman/5.6/en/replication-gtids-howto.html)

Add a cube with a pre-aggregation.
Will fail with an error like `"Error: ER_GTID_UNSAFE_CREATE_SELECT: Statement violates GTID consistency: CREATE TABLE ... SELECT."`

**Expected behavior**
Pre-aggregation queries should be safe for statement based replication as well as replication with GTIDs.
