During DDL operations triggers of old space and new created space
are swapped. This leads to crash in case if this swap occurs from
space on_replace triggers. This patch banned all DDL operations
from on_replace triggers.

Title: Ban DDL operations from space on_replace triggers

Previously user can set function for space on_replace trigger,
which performs DDL operation. This may leads to tarantool crash,
that's why this patch bans DDL operations from on_replace triggers.
All this operations fails with error: "Space on_replace trigger
does not support DDL operations".
