hinfo: Adding basic skeleton based on hbal

It prints the information which hbal prints in a nice formatted manner and of
course without doing any actions. An example output looks like this:

$ hinfo -m xen.example.com
Loaded 4 nodes, 2 instances
Cluster has 1 node group(s)...

Temporary fix for hspace's NPU calculation

hspace computes the NPU (normalised CPU units) via the
(used|pool|avail) VCPU divided by the (currently cluster-wide) max
vcpu_ratio.

However, in the future we'll have variable vcpu_ratios, so we can't
the calculation as such. We temporarily change to computing the...

Switch over some hspace stats from RSpec to AllocInfo

This patch changes the allocation delta stats from RSpec to
AllocInfo. There's nothing interesting about it, but it should allow
more correct computations of Npus in hspace.

I also moved the AllocStats type alias from Cluster.hs to Types.hs...

Parse options in htools.hs, not in each program

This patch moves the call to getArgs/parseOpts into htools.hs, as
opposed to the current situation where htools.hs only calls the main
file of each program, which in turn calls these two functions.

By doing it only once we remove some duplicate code and we also export...

Show explicit message when hspace fails to alloc

Currently, in the human-readable mode, hspace doesn't show any
messages when no instances can be allocated in tiered-alloc mode. This
is confusing, so let's add an explicit message.

Switch hspace defaults to the cluster policy

This changes from the current hardcoded defaults to the cluster
policy. The command line options now override the defaults from the
cluster, and the tiered spec mode is always enabled.

Also fixes a tiny typo in the man page (together with the man page...
