Foreign key checks on MySQL >= 5.5.7 for TRUNCATE

- Added `ConfigurablePlatform` interface to set the connection
  parameters to the Platform
- Connection is now setting the parameters to the Platform if it
  implements `ConfigurablePlatform`
- `MySQLPlatform::getTruncateSql()` now checks for a new param
  `disable_fk_checks`, if it is true and the version is affected, it
  automatically adds the required SQL.
