Branch: http://github.com/tarantool/tarantool/tree/kshch/gh-3273-no-sql-triggers
Issue: https://github.com/tarantool/tarantool/issues/3273

To move Triggers to server, we introduced special field sql_triggers 
in space struct. All triggers AST objects are stored in global Hash
db->pSchema->trigHash. Space refer to trigger AST by pointer, but not hold it.
All trigger actions operated with on_replace_dd_trigger that compiles
AST, makes all related checks(e.g. that other _trigger tuple fields
match extracred values), and does insertion in Hash and List in space.

To support LUA deletions we have changed _trigger space format to contain
space_id as secondary key: on space delete in LUA code we obtain relative 
_trigger tuples and pop up them from their space. This cause triggering
on_replace_dd_trigger that removes them from the sql_triggers list in space
and Cache, so on final space_delete no SQL trigger should be present in DB.
