htools: add more IAlloc data types and functions

These move the 'not supported' message deeper into the workflow;
assuming that the workflow as added by this patch is correct, all that
remains is:

- for disk template DRBD8, plug in the currently existing mechanisms...

htools: read the disk template in Luxi and Rapi

Both these backends already have the data, we just need to use it.

htools: add DiskTemplate to instance definition

Currently always fixed to DRBD8, as that is what we assume already.

htools: simplify some JSON-related code

Instead of manually encoding the JSValue(s), we can use showJSON as
long as we use data types that can be auto-converted.

htools: allow different result types

This patch extends the previous patch changes to allow that each
Cluster function returns a different result type, as long as we have
an auxiliary function that processes that into the standard
IAllocResult type.

htools: start reorganising the IAllocator workflow

Currently, all IAllocator requests return the same result type: a list
of strings (usually nodes, but can also be instance:nodes). This won't
be true in the future, with the new request types that will return...

htools: split more code from hail/main

The logic of request processing is not separated into its own
function, and (beside CLI interaction, e.g. verbosity handling) all
logic is now in IAllocator.hs.

htools: move code from hail.hs to IAllocator.hs

This will make it easier to unittest the code, and keeps all login in a
single module.

htools: add parsing of input node-evac messages

This is a lot of duplication with modeMreloc, which will get sorted
out once we convert mreloc to change-group.
