Add a custom CLI module for DataCollectors

Currently, the mon-collector binary uses the HTools/CLI module, which
is OK but mean it links in lots of htools code. By copying that module
to DataCollectors/CLI and removing the unneeded code, we reduce the
number of modules it depends on fro 20 to 12, meaning both a shorter...

Add a type alias for the personality lists

The signature of the personality definitions is so ugly that, at
least, we should hide it a bit behind a type alias.

Introduce generic multi-command binary handling

Currently, the mon-collector binary is the only multi-command binary
we have in Haskell. Not surprisingly therefore, its command line
handling is not as robust as we need, not being able to support
standard "--help" commands....

Allow shutting down offline instance

If an instance is offline we definitely shouldn't start it up.
But shutting it down, should it be up by mistake is not "that" bad.
Still, we only allow it with --force, as it still performs an action on
an instance we shouldn't touch. This should make everybody happy....

Switch Luxi sendMsg from strict to lazy ByteStrings

Commit e821050d (“Switch the Luxi interface from Strings to
ByteStrings”) was designed to optimise the receive interface, but has
an unfortunate side-effect: when sending non-trivial messages, it
means that both the entire String and the ByteString versions must be...

Add NFData instances for query results

This allows us to ensure that query results are strict as we build
them, instead of being lazy and only evaluated when the reply is sent
over the Luxi interface.

Introduce NFData instances for JSON types

The JSValue/JSObject types don't come with a NFData instance, so let's
add one ourselves, so that we can force evaluation of JSValues (either
when building or when reading them).

Fix parsing of absolute job dependencies

It seems that Python code generates (sometimes) absolute job
dependencies which are strings, instead of integers, so we should be
able to parse these as well. We simply change from explicit int-based
parsing (makeJobId) to the generic one (parseJobId)....

Make two common opcode parameters always serialised

This changes deps and comment fields to always be shown, to match the
Python behaviour for (at least) job listing/ops field.

Fix disk_template OpInstSetParams parameter

This is not a required field, but rather an optional one; we add a new
parameter and use it instead.
