Julius Volz 140eede5e0 Rename UNREACHABLE to UNHEALTHY.
The current wording suggests that a target is not reachable at all,
although it might also get set when the target was reachable, but there
was some other error during the scrape (invalid headers or invalid
scrape content). UNHEALTHY is a more general wording that includes all
these cases.

For consistency, ALIVE is also renamed to HEALTHY.
