[3AceShowHand]

What problem does this PR solve?

What is changed and how it works?

cdc prerestart and postrestart method, remove status check, since after the instance restart, it would cost a few seconds to be available.

• this prevent false detect that a new start cdc instance is down, since it will be available just a few seconds later, around 3 ~ 5s seconds.
• When all cdc instance is down, for upgrade / scale-in, this would cost a little longer time to guarantee that the instance is down now, which is acceptable.
• adjust the timout for get capture open api to 10s, this should be long enough.

Check List

Tests

• Manual test (add detailed scripts or steps below)

• Deploy 2 cdc capture, restart the first one, the second one should perform the prerestart and postrestart as expected.
