    Fix extension server_meta follow API v3 rules
    
    * add decorator expected_errors
    * change 'meta' to 'metadata' for show and update that is
    consistent with other actions
    * use is_valid_body instead of catching AttributeError and ValueError,
    because AttributeError and ValueError is too generic.
    
    Partially implements bp v3-api-extension-versioning
