Dmitry Simonenko c8563b2d46 Add distributed_exec() function
This function allows users to execute a SQL query on a list of data
nodes. The purpose is to provide users a way to, e.g., create roles on
data nodes.

The current implementation is quite straightforward. Just execute any
provided query on a list of data nodes. The query will execute with
the current user role. The function does not return or print any
result values. In case of error, it will print the data node name and
a related error message.
