[RSS] Bot -> HS error in the Integration Manager's page

[opk12]

Not pushing, just throwing an idea up in the air.

If the bot knows that there was a Bot <-> HS error (as it seems from some comments of #844), should the error appear in the Integrations Manager dialog?

Maybe having an error under Recent feed results, in addition to Successful fetch, would help discover and report any failures in the future.

I don't know if it is feasible? The dialog is loaded from integrations.ems.host, not the HS, so a failure to send to the HS can be logged somehow?

The problem is in theory even Bot <-> HS errors should be retried, and they should be invisible ideally. I'm worried about bubbling up operational problems like homeserver flakiness to the user, whereas the feed fetch failures are more understandable to the user.
