Implement a SQL schema migration service based on an actual
parser for CREATE TABLE statements that are mapped to Doctrine
Table objects. This enables the use of the Doctrine DBAL
SchemaManager for all schema modifications.

The new Schema migration service is fully aware of multiple
database connections and normalizes MySQL specific data types
to standard compliant types. This mostly affects the TINYINT
data type which gets converted to a SMALLINT.
