Fix tag exclusion weight

Currently, the tag exclusion metric has a weight of one, which means
there might be cases where we won't move instances around because it
upsets the cluster metrics. However, we do want to make a higher effort
for cleaning up tag collisions, so we increase the weight to an...

Also adds them in hbal.

Add new CLI options for min gain during balancing

Recent hbal seems to run many steps for small improvements (< 1e-3), so
we should stop early in this case.

We add a new option (-g), that will be used for the minimum gain during
balancing. This check will only become active when the cluster score is...

Add some more debugging functions

These are just variations of the standard debug, but are provided for
simpler code, since lazyness is something causing non-computation of
debug statements.

Fix ReplaceSecondary moves for offline nodes

The addition of a new secondary on a node is doing two memory tests:
- in strict mode, reject if we get into N+1 failure
- reject if the new instance memory is greater than the free memory (not
available memory) on the node...

Change iterateAlloc to return the instance list

The Cluster.iterateAlloc and tieredAlloc functions are changed to also
return the updated instance list, since it is needed to have a “full”
cluster view.

Abstract the cluster serialization from hscan.hs

This is currently hardcoded in an internal function in hscan.hs, and we
move it to Text.hs for later use.

Add a new option --save-cluster

This option will in the future be used to serialize the cluster state in
hbal and hspace after the rebalance/allocation steps.
