[Feature][Sort] Add metric computing of MySQL and PostgreSQL and HBase for user query metric by label

[gong]

Description

Add metric computing of MySQL and PostgreSQL and HBase for user query metric by label value groupId or streamId or nodeId

Use case

User only need add with param "inlong.metric":"<groupId>&<streamId>&<nodeId>" when use flink sql.
example:

  create table `table_groupId_streamId_nodeId1`(
    `age` INT,
    `name` STRING,
    PRIMARY KEY(`age`) NOT ENFORCED)
    WITH (
    'connector' = 'postgres-cdc-inlong',
    'hostname' = 'ip',
    'port' = '5432',
    'username' = 'postgres',
    'password' = 'inlong',
    'database-name' = 'postgres',
    'schema-name' = 'public',
    'table-name' = 'user',
     'decoding.plugin.name' = 'pgoutput',
  'slot.name' = 'feaafacbaddadc',
   'inlong.metric' = 'pgGroup&pgStream&pgNode1'
);

CREATE TABLE `table_groupId_streamId_nodeId2`(
    PRIMARY KEY (`name`,`age`) NOT ENFORCED,
    `name` STRING,
    `age` INT)
    WITH (
    'connector' = 'print'
);

   INSERT INTO `table_groupId_streamId_nodeId2`
    SELECT
    `name` AS `name`,
    `age` AS `age`
    FROM `table_groupId_streamId_nodeId1`;

we can set flink-conf.yaml add metric report

metric.reporters: promgateway
metrics.reporter.promgateway.class: org.apache.flink.metrics.prometheus.PrometheusPushGatewayReporter
metrics.reporter.promgateway.host: ip
metrics.reporter.promgateway.port: 9091
metrics.reporter.promgateway.interval: 60 SECONDS
metrics.reporter.promgateway.filterLabelValueCharacters: false

we can see metric in pushgateway.

I will add this feature for mysql cdc and postgresql cdc and HBase.
