Add query option to control invalidate all metadata

Hi all,
We can use 'invalidate metadata' to invalidate all metadata, but this is a heavy operation. Sometimes we would rather restart catalogd instead of execute 'invalidate metadata’. Maybe it’s better to add a query option to control the global 'invalidate metadata'. Set this query option default value as false to forbidding this operation.
