[Feature Request] - strict update mode

[imiskolee]

hi,team:

I am trying to design a feature called strict update mode. it's meaning just allow execute UPDATE SQL with the primary key or which configured fields. the proxy will reject the update SQL when can't match configure.

Samples:

configure:

table1: just allow update with the primary key.
table2: just allow update when included user_id or id on where clause.

examples:

update table1 field_1 = 1 where id = 1. [pass]
update table1 field_1 = 1 where field_2 = 1. [reject]
update table2 field_1 = 1 where id = 1. [pass]
update table2 field_1 = 1 where user_id = 1 [pass]
update table2 field_1 = 1 where field_2 = 1. [reject].

how about the idea?
