PHOENIX-933 Local index support to Phoenix

This is the actual code. Earlier by mistake I missed to add LOCAL in if branch so if else branches are same. 
            if (localIndex) {
                ddl = "CREATE LOCAL INDEX " + INDEX_TABLE_NAME + " ON " + DATA_TABLE_FULL_NAME + " (date_col)";
            } else {
                ddl = "CREATE INDEX " + INDEX_TABLE_NAME + " ON " + DATA_TABLE_FULL_NAME + " (date_col)";
            }

Now I have corrected it.
