Make SubmitOpCode expect options without print_jobid

As opposed to SubmitOrSend, the SubmitOpCode function is
called also by commands not supporting submit options. Hence
only inspect these options, if they are actually present.

Add an option to print job id of submitted jobs on stdout

When submitting a job, the job id, prefixed by 'JobID: ', is output to
stderr. While this is easy to understand for humans, for scripting, it
is more convenient to have (additionally) the id on stdout (and only...

Add type annotation to avoid monomorphism restriction

Even though we need the let-bound variable showMoves only
at type [(String, String)] -> IO (), it's most general type
would be (PrintfArg a, PrintfArg b) => [(a, b)] -> IO ().
This causes the monomorphism restriction apply to that binding,...

add option --print-moves to hroller

If non-redundant instances are present in the cluster, hroller will
plan for them to move to other nodes while the group is rebooted.
This adds an option to also show this plan.

hspace prints info about spindles

Statistics about spindles are tracked. In human-readable output, spindles
are printed only when used (i.e., exclusive storage is enabled). For

Spindles become part of htools resource spec

When exclusive storage is enabled, spindles are used instead of disk space
to compute the cluster score.

Comments and variable names in computePDsk has been changed to match the
actual code.
