[HZ-566] SQL: CREATE INDEX implementation

[Fly-Style]

CREATE INDEX was fully implemented.
Grammar :

CREATE INDEX [ IF NOT EXISTS ] name ON map_name ( column_name [, ...] )
[ TYPE ( SORTED | HASH | BITMAP ) ]  
[ OPTIONS ( 'option_name' = 'option_value' [, ...] ) ]

Options are available only for BITMAP index since it has additional BitmapIndexConfig. Those options are supported:

• unique_key
• unique_key_transformation.

In case of SORTED/HASH index, options usage causes QueryException.

DROP INDEX syntax was supported, but not the execution path (DROP INDEX query throws UnsupportedException).

We don't test duplicate options.

[Fly-Style]

For map.addIndex(IndexType.SORTED, "this", "this"); :

java.lang.IllegalArgumentException: Duplicate attribute name [attributeName=this, indexConfig=IndexConfig{name=null, type=SORTED, attributes=[this, this]}]

[Fly-Style]

It means, both test and check are makes sense.

[viliam-durina]

I mean duplicate OPTIONS, not attributes.

[Fly-Style]

Ah, sorry. You pointed to indexArgsCannotBeDuplicatedTest(), and I immediately switched to args context :)

I always add comments to some code line. Comments added to the whole PR cannot be marked as resolved.
