Alert section for freshness checks

[dpeng817]

Adds an alerts section to the freshness guide.

I originally wanted to make more sweeping changes here, but it's proving more difficult than I thought. I think the biggest outstanding problem with the guide is thelack of reference to alerting (main important thing about freshness, so let's fix that first).

Should we instead add this section to the asset checks page and link to it from the freshness checks page?

@sryza Which asset check page - this main category one, or this guide for defining checks? What's the thinking behind moving it?

I honestly didn't think that far - I could see either, or even a third one.

What's the thinking behind moving it?

These instructions aren't really specific to freshness checks in particular. They apply for other asset checks as well.
