Introduce LIKE Operator

[atris]

This commit introduces LIKE operator as defined by SQL92 standard.

Currently, our only way to be matching text fields is to either define regexes and use REGEXP_LIKE or define Lucene syntax and use TEXT_MATCH function.

SQL 92 defines the LIKE operator, which allows for exact matches (FOO like "BAR") and subquery matches (FOO LIKE "%AR").

Having the LIKE operator brings us closer to the SQL standard, allows users to migrate to us in an easier form and allows third party SQL tools to work on top of us.

@siddharthteotia Does text match has same semantic as sql like? I thought text match uses the lucene query syntax

[Jackie-Jiang]

Syntax for SQL LIKE: https://www.w3schools.com/sql/sql_like.asp

[siddharthteotia]

TEXT_MATCH uses Lucene query syntax for term, phrase, regex, fuzzy, boolean etc queries. Is SQL LIKE compliant with lucene query syntax ?

No, it is not. I have updated the PR to reflect the same.
