[FEATURE][TOOLS-CDC]:add flink Command line support

[xxsc0529]

Summary

When synchronizing data to OceanBase, the flink CLI is supported. close #101

Solution Description

Define program entries, receive parameters, and parse them. Use Oceanbase Catalog to obtain the information required by Flink and create the corresponding sink。Here's how it works.
`CREATE TABLE test_history (
itemid BIGINT NOT NULL,
clock INT DEFAULT 0 NOT NULL,
value DOUBLE PRECISION DEFAULT 0.0000 NOT NULL,
ns INT DEFAULT 0 NOT NULL,
PRIMARY KEY (itemid, clock, ns)
) ;

CREATE TABLE test_history_uint (
itemid BIGINT NOT NULL,
clock INT DEFAULT 0 NOT NULL,
value DECIMAL(20,0) DEFAULT 0 NOT NULL,
ns INT DEFAULT 0 NOT NULL,
PRIMARY KEY (itemid, clock, ns)
) ;

CREATE TABLE test_history_str (
itemid BIGINT NOT NULL,
clock INT DEFAULT 0 NOT NULL,
value VARCHAR(255) DEFAULT '' NOT NULL,
ns INT DEFAULT 0 NOT NULL,
PRIMARY KEY (itemid, clock, ns)
);The command line is as follows./bin/flink run
-Dexecution.checkpointing.interval=10s
-Dparallelism.default=1
-c com.oceanbase.connector.flink.tools.cdc.CdcTools
lib/flink-connector-oceanbase-tools-cdc-1.4-SNAPSHOT.jar

--database test_db
--mysql-conf hostname=xxxx
--mysql-conf port=3306
--mysql-conf username=root
--mysql-conf password=xxxx
--mysql-conf database-name=test_db
--including-tables "tbl1|test.*"
--sink-conf username=xxxx@xxxx
--sink-conf password=xxxx
--sink-conf url=jdbc:mysql://xxxx:xxxx
--sink-conf sink.label-prefix=label
--table-conf replication_num=1`
The sink-config configuration is the configuration of the OceanBase database
