Parse healthcheck response

[aagrxyz]

The healthcheck response, that we get is stored verbatim (i.e. the raw html). This is a lot overkill and we do not need to store the entire html response. We need to develop some heuristics on what to store, parse the message accordingly and then store the result. Some ideas are:

1. Store just the title of the page if it is HTML
2. Store just the raw text if it is not a HTML
3. If there is no title, store the first h1 tag or the head tag
