This is a major update of CONNECT that goes from version 1.1 to 1.2

===================================================================
- Implement a first support of the ALTER TABLE command. This fixes MDEV-5440
  but does much more than only that. See the details of how ALTER is supported
  in the new documentation and also in MDEV-5440 comment.
  This is done principally by implementing for CONNECT the virtual function
  check_if_supported_inplace_alter.
