Yury Gerzhedovich updated IGNITE-16961:
---------------------------------------
Description:
Let's add prepared statement support.
* avoid extra sending query parameters (incl. query text) after server-side
statement object has been created (unless client re-connect happened)
* avoid query planing more than once (unless client re-connect happened or
schema has been changed).
* release server resources when statement was closed or session was
invalidated.
