DRILL-3747: basic similarity search with simmetric
Helps handling i.e. typos in search queries with popular algorithms like
levenshtein.
Sample query:
```
select levenshtein('foo', 'boo') from (VALUES(1)); //gives 0.67
```
and
```
select levenshtein('foo', 'bar') from (VALUES(1)); //not similar - gives 0
```
