-- Terminates an active session. A @TerminateSession@ call on a session
-- that is already inactive (for example, in a @FAILED@, @TERMINATED@ or
-- @TERMINATING@ state) succeeds but has no effect. Calculations running in
-- the session when @TerminateSession@ is called are forcefully stopped,
-- but may display as @FAILED@ instead of @STOPPED@.
