adjustSignedUnsignedZerofill

private String adjustSignedUnsignedZerofill(StringBuilder origin)

This method will adjust the suffix names of numeric data type. In connector streaming phase, the ddl parser maybe meet the invalid definition of suffix names with numeric data type, will adjust to appropriate values. e.g. replace "SIGNED UNSIGNED ZEROFILL" or "SIGNED ZEROFILL" to "UNSIGNED ZEROFILL", "SIGNED UNSIGNED" to "UNSIGNED" and adjust to "UNSIGNED ZEROFILL" if "zerofill" appears alone.
