Olivier Bertrand e4797a991f In CONNECT version 1.6.10 NOSQL facility is enhanced by a new way to retrieve NOSQL data.
In addition to files and Mongo collections, JSON as well as XML and CSV data can be retrieved
from the net as answers from REST queries. Because it uses and external package (cpprestsdk)
this is currently available only to MariaDB servers compiled from source.

-- Also include some changes specific to MariaDB 10.3.
  modified:   storage/connect/CMakeLists.txt

-- Add conditional REST support
