[Feature][Manager] Support configuration of subscription name for pulsar source

[aloyszhang]

Description

Currently, we can't set the subscription name for the pulsar source,

Flink connector will generate a subscription name combining flink-sql-connector-pulsar prefix with a random string suffix. This may lead to the flink job failing due to the subscription not existing in the pulsar broker(the pulsar broker may disable the auto-creation of subscription).

Use case

Manager supports setting the subscription name for the pulsar source and passes the parameter to flink-pulsar-connector.
