### What changes were proposed in this pull request?
`LIKE ANY/SOME` and `LIKE ALL` operators are mostly used when we are matching a text field with numbers of patterns. For example:
Teradata / Hive 3.0 / Snowflake:
```sql
--like any
select 'foo' LIKE ANY ('%foo%','%bar%');
--like all
select 'foo' LIKE ALL ('%foo%','%bar%');
```
PostgreSQL:
```sql
-- like any
select 'foo' LIKE ANY (array['%foo%','%bar%']);
-- like all
select 'foo' LIKE ALL (array['%foo%','%bar%']);
```
This PR add support these two operators.

### Why are the changes needed?
To smoothly migrate SQLs to Spark SQL.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Unit test.

Spark SQL
This module provides support for executing relational queries expressed in either SQL or the DataFrame/Dataset API.
Spark SQL is broken up into four subprojects:
- Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
- Execution (sql/core) - A query planner / execution engine for translating Catalyst's logical query plans into Spark RDDs. This component also includes a new public interface, SQLContext, that allows users to execute SQL or LINQ statements against existing RDDs and Parquet files.
- Hive Support (sql/hive) - Includes extensions that allow users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allow users to run queries that include Hive UDFs, UDAFs, and UDTFs.
- HiveServer and CLI support (sql/hive-thriftserver) - Includes support for the SQL CLI (bin/spark-sql) and a HiveServer2 (for JDBC/ODBC) compatible server.
Running ./sql/create-docs.sh generates SQL documentation for built-in functions under sql/site, and SQL configuration documentation that gets included as part of configuration.md in the main docs directory.
