Use updated flyway_schema_history table name

[Mufasa]

flyway changed the name of the schema history table from schema_version to flyway_schema_history from v5.0.0 onwards. Your FlywayFactory class still seems to use the old name (line 28 - private String metaDataTableName = "schema_version";).

This causes the following warning to be logged when validating the schema:

WARN JdbcTableSchemaHistory:53 - Could not find schema history table my_db.flyway_schema_history, but found my_db.schema_version instead. You are seeing this message because Flyway changed its default for flyway.table in version 5.0.0 to flyway_schema_history and you are still relying on the old default (schema_version). Set flyway.table=schema_version in your configuration to fix this. This fallback mechanism will be removed in Flyway 6.0.0.

I know that I can override this default by adding this to my dropwizard YML file:

flyway:
metaDataTableName: flyway_schema_history

But I was wondering if this default can be changed to match the current flyway default?
