Merge r427172 from trunk:

Add in a very simple balancer "set" concept, which allows
for members to be assigned to a particular cluster set
such that members in lower-numbered sets are checked/used
before those in higher ones.

Also bundled in this are some HTML cleanups for the balancer
manager UI. Sorry for the mixins :)

Compiles/builds clean: passes test framework as well
as more normal usage tests ;)

Merge r427368, r428352, r428361, r432352 from trunk:

Reset standby flags for each loop through the cluster sets


Initialization change. Move to a different format
to force resets as well as a common technique, in case
_route is updated at some point.


Update docs for proxy:

  1. Put params in abc order
  2. Add hot-standby example
  3. Add in new features that hadn't been documented yet (lbset, ...)

The number of times elected as well as the i/o

Restructure the find_route_worker() function. Basically,
it should take care of knowing about usable and unusable
workers. By centralizing this logic, it will make it
easier and more streamlined to add in the forthcoming
hot-standby status workers.

Clean up some proxy macros. Avoid the use of magic
numbers, and instead use pre-defined defines. Also,
ensure that usable workers have been initialized :)

Allocate a bit for hot standbys. Adjust so that
normal "usable" workers don't count these.

Add in hot-standby balancer member. If all other members
are disabled or not-usable, ONLY THEN will the hot
standby's be used.
