CLI: Prevent incompatible options to be selected

This patch makes CLI abort if more than one backend is selected.

Add support for luxi backend in CLI/hspace/hbal

This patch changes the backend selection method in CLI to prefer, in order:
- a RAPI specification
- a Luxi specification
- and finally the node/instance files

It also modifies hspace and hbal to provide a ‘-L’ command line option...

Initial commit of the luxi backend

This patch adds a luxi backend that allows direct query of the master
daemon on the local node. This patch doesn't enable the backend to be
used.

There are a couple of things still missing in the implementation:
- we don't have a master timeout in reads and writes, only a...

Introduce timeout in RAPI queries

The patch adds two constants in Types.hs for connect and query timeout,
then modifies Rapi.hs to use them as the connect and general curl
timeout.

Rapi could be improved more, as currently we wait double the total
timeout due to not aborting early in case the node queries failed.

hspace: fix failure handling of tryAlloc results

Currently hspace doesn't handle failures from tryAlloc correctly; this
patch changes the iterateDepth function in hspace to return a Result (…)
so that errors can be propagated correctly.

The patch also changes one output key to be more clear and a typo in...

Change the tryAlloc/tryReloc workflow

Currently, the tryAlloc and tryReloc function return a list with all the
results, both failures and successes. This is fine for hail, which does
one round of allocations, but is not so good for hspace, which does
iterative rounds; since at each (successful) step we only take the best...

Simplify the Cluster.tryAlloc structures

Currently the tryAlloc function calls the
allocateOnSingle/allocateOnPair and the builds a new tuple with those
functions's result plus the new node list. This is however suboptimal
in two respects:
- the new nodes added are the 'old' versions of the respective nodes,...

Slight change to the internal allocation results

Currently the Cluster.AllocSolution type is defined as a list of
‘(OpResult Node.list, …)’ and the results for applyMove are defined as
‘(OpResult Node.List, …)’. Both these means that the failure/success
indication is hidden in the first elements of this tuple, which makes is...

hspace: switch output to shell-script format

This (big) patch changes the output of hspace from text-format
(separated by ‘: ’) to a shell-snippet, in ‘key=value’ format.

This will allow sourcing the output or parsing it via awk/sed/etc.
