Fixes for TS-3720
The first commit here is to revert @SolidWallOfCode 's commit that has
broken it right now. We actually had a long conversation about this on IRC and
we'd prefer a better solution, but at least for now this has broken
last_failure checking completely. I'm going to take a crack at maintaining a
map of the port health separately, but I'm not sure how hard it'll be.
The second commit makes all 3 LB methods check the status of the real,
instead of just default (which isn't even RR BTW).

Make HostDBRoundRobin::select_best_http take last_failure time into
consideration for all RR types
In the current setup it only checks that status of the reals if you use
"default RR" (which is actually consistent hashing... but we'll let that
slide). This patch consolidates the alive() check into the HostDBInfo struct,
and then calls if from all 3 LB mechanisms. Since you can control if/when a
host is marked as down in ATS there is no reason to not check.
Issue: TS-3720
