iPolicy: enable by default all storage templates

… otherwise we can't run tests or simulations using non-default
templates. Tests still pass.

Add a helper type and function for the mirror type

Currently we track the mirroring type as simply yes/no, with "yes"
meaning DRBD. This is not enough for handling shared storage, so we
need to add a type that gives the exact mirroring type (none,
internal, external), and a function that ties the disk template type...

Add spindle ratio to htool's IPolicy

Just the usual data/type declarations, read/save in the text backend,
etc. Also does a bit of unit-test cleanup (the way we build
ipolicies).

htools: allow rbd disk template

Notes:
- it'd be nice if there was a way to automatically generate the
DiskTemplate list instead of manually specifying it. After all we

Add vcpu_ratio definition to the IPolicy type

This will be "naturally" read in the JSON-based backends (Luxi/Rapi),
and we add explicit code for handling it in the Text backend.

Add a new type for holding allocation statistics

The current RSpec type doesn't cut it anymore (and it's used in other
places), so let's introduce a separate type for holding these
statistics.

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...

More reshuffling of code

Following the split Types/BasicTypes, we can remove the last
JSON-related stuff from Utils.hs, and do some more cleanup.

htools: split parts of HTools/Types.hs into BasicTypes.hs

The 'Result' type is common and:

- might be used outside of HTools-specific code too
- is better split as we need these basic types for building the more
complex ones in Types.hs

This changes the names for some helper functions so that future

This is similar, but not identical, to Utils.ParseUnit. The biggest
difference is that we don't round up/down; as we only use integral
