STORM-2170 Add built-in socket datasource to runtime
* Add Socket datasource (input/output) in storm-sql-runtime module
* only for test purpose, no guarantee
* scheme: 'socket'
Since Socket datasource is in storm-sql-runtime, it's registered to
DataSourcesProvider by default.
So below SQL statements doesn't need any external artifacts at all and can
be executed to below command:
```
./bin/storm sql apache_log_error_filtering_socket.sql
apache_log_error_filtering_socket
```
```
CREATE EXTERNAL TABLE APACHE_LOGS (ID INT PRIMARY KEY, REMOTE_IP VARCHAR,
REQUEST_URL VARCHAR, REQUEST_METHOD VARCHAR, STATUS VARCHAR,
REQUEST_HEADER_USER_AGENT VARCHAR, TIME_RECEIVED_UTC_ISOFORMAT VARCHAR, TIME_US
DOUBLE) LOCATION 'socket://localhost:8889'
CREATE EXTERNAL TABLE APACHE_ERROR_LOGS (ID INT PRIMARY KEY, REMOTE_IP
VARCHAR, REQUEST_URL VARCHAR, REQUEST_METHOD VARCHAR, STATUS INT,
REQUEST_HEADER_USER_AGENT VARCHAR, TIME_RECEIVED_UTC_ISOFORMAT VARCHAR,
TIME_ELAPSED_MS INT) LOCATION 'socket://localhost:8890'
INSERT INTO APACHE_ERROR_LOGS SELECT ID, REMOTE_IP, REQUEST_URL,
REQUEST_METHOD, CAST(STATUS AS INT) AS STATUS_INT, REQUEST_HEADER_USER_AGENT,
TIME_RECEIVED_UTC_ISOFORMAT, (TIME_US / 1000) AS TIME_ELAPSED_MS FROM
APACHE_LOGS WHERE (CAST(STATUS AS INT) / 100) >= 4
```
Manually tested via opening tcp servers via netcat.
