Feat: Alter Source|(Table with conns)'s connector's parameters in with option

[st1page]

ALTER TABLE/SOURCE <table name> CONNECTOR [CLEAN STATE] WITH (…)

• without CLEAN STATE
  • In this case, just modify the stored parameters in the streaming plans
• with CLEAN STATE, the user can change the table's connector.

In this case, just modify the stored parameters in the streaming plans

Does this mean users can do whatever they want as long as not changing the connector?
TBH, I vote for this behavior because it is hard to tell whether we should enforce clean state in some cases, eg. broker SSL cert expires and the broker is mounted to another domain. RisingWave cannot see the two broker_addrs as the same.
