Description
Today we require changefeeds operators to do the following in order to change options, certs, or other changefeed properties:
```
PAUSE
ALTER CHANGEFEED ...
RESUME
```
We could make this a more seamless experience by doing the PAUSE/RESUME steps under the hood during the ALTER CHANGEFEED statement. We should only RESUME if the changefeed started in a paused state. We would need to decide what state we leave the changefeed in if an error happens during the ALTER CHANGEFEED.
