MigrationContext sets the context in which a migration is run.
A migration context requires the path to the migrations is set in the migrations_paths parameter. Optionally a schema_migration class can be provided. For most applications, SchemaMigration is sufficient. Multiple database applications need a SchemaMigration per primary database.
