Add integration tests to bulk spanner migration for checking MySQL data type support (#3046)
* Add missing data type mappings to data types integration test * Add data types test for bulk migration from MySQL to a Postgres dialect Spanner DB * Improve check for bit to string data type mapping Also, add missing tables to PG dialect spanner schema * Split PG dialect test into its own test class * Remove unused code * Reduce maxConnections to 4 in an attempt to avoid exceeding the max connection limit of the MySQL DB
