Fix a few issues found by newer hlint

Testing with a newer hlint found a few minor issues; but all are real,
valid recommendations:

- don't use "if cond then f x else f y", but "f (if cond then x else y)"
- "if a then b else True" is equivalent to the simpler "not a || b"...

Add support for optional fields with null serialised

This follows a conversation we had for how to deal with
optional-but-required fields in JSON serialisations: fields which are
optional (can be either a given type or 'null'), but where the 'null'
value is required. There are just a few of these in the Python code,...

Errors.hs: improve field names for ConfigVersionMismatch

Change {exp,act}Code to {exp,act}Ver, which gives a better idea that
the integer fields represent version numbers.

Also:

- errors.py: update OpPrereqError's docstring to note that an error
    code is always expected as the second argument (it was previously...

Convert query path from string errors to GanetiException

This patch converts all the call paths from 'Result' (which contains
just string errors) to 'ErrorResult', which holds
GanetiException-encoded errors. We can now return proper
OpPrereq/OpExec errors to the clients of the luxi/query socket....

Add exception utility functions

In Python, formatError also returns the exit code, but I find that
splitting them leads to clearer code.

Add an Errors module mirroring the Python one

As described in the module doc string, while writing this it dawned
upon me that we're mixing all errors together into a single hierarchy
(well, type on the Haskell side), which is not good. Some errors are
used purely within noded, some in the CLI frontends, etc. so these...

Abstract Luxi template functionality

These are almost generic, so let's change the signatures a bit a make
them fully so.

Abstract a few types in THH.hs

This 'simple' way of defining objects will be used also for errors, so
let's make it less Luxi-specific.

Fix setting of 'failN1' flag for corner case

This patch includes:

  • The 'failN1' flag is now only set if there is strictly less
    memory available than required for failover.
  • Unit tests for that.
