[patches] [schema 1/1] Allow to do not specify tail nullable index columns

[Konstantin Osipov]

> If a column is nullable and is the last defined one (via index parts
> or space format), it can be omited on insertion. Such absent fields

> Closes #2988

Some raw thoughts: 

- maybe we should add another key part property, let's call it
  is_optional, to remove the performance impact on people not
  using the feature?

I know this could complicate the patch quite a bit.
