cmdlib: Opportunistic locking on instance creation

Adds a new parameter to “OpInstanceCreate” and “OpInstanceMultiAlloc” to
use opportunistic locks.

Add types and parameters for common opcode implementation

This will go into a separate type; this patch adds the needed
underlying types and parameters.

Rework custom fields handling

This patch changes a bit the handling of custom fields. Since in
general we use custom fields to aggregate multiple entries in the JSON
object into a safer data-type, we should also have a way to declare
which extra entries this field covers (so that in the future we can...

Add a few missing fields from opcodes

Due to manual conversion, a few fields were missing from the
conversion, but as they were optional our type equivalence checking
didn't detect this.

Add two last missing opcodes

OpInstanceQuery was missing accidentally, whereas OpRestrictedCommand
was just recently added without Haskell definitions.

The patch also slightly improves the OpNodeQuery arbitrary generation.

Abstract query common opcode definitions

It would be even better if the opcodes would actually have all the
same definitions, until then we have two sets of definitions.

Remove remaining in-line parameters

… except one, and replace them with separately-defined ones in
OpParams.

Remove read instances from our Haskell code

It turns out that optimising 'read' derived instances (via -O) for
complex data types (like OpCode, or the various objects) can be slow
to very slow. Disabling such instances results in (time make
$all_our_haskell_binaries) large compile-time savings and also smaller...

Complete the instance OpCodes and parameters

Only the original instance opcodes (used in htools) are left
non-converted to only parameter style; they'll be cleaned up later,
once the htools codebase itself migrates to safer types.

Add Group, OS and Backup opcodes

This also corrects a docstring in OpBackupExport on the Python side.

Complete the Tag opcodes and fix OpTestDelay missing param

The regexp in OpTagsSearch is loaded as is, without testing for
validity; the rest of the patch is trivial.

Complete the Test opcodes

This adds the OpTestAllocator, OpTestJqueue and OpTestDummy
opcodes. The OpTestAllocator seems to need some cleanup (on the Python
side), for now we implement it as is. As for the other two, while not
used in production, we should have full coverage for them as well....

Add types, parameters and the opcodes for networks

This completes the last missing opcode group. The only difficulty was
with the ip addresses, where we used simple strings to represent them
and (for IPv4) a few helpers to generate arbitrary instances;
otherwise, the patch is trivial....

Add types and parameters for OpInstanceCreate

This is a "big" opcode, so sending it separately.

A few types needed changing, and a few parameters were renamed to make
it more clear which are cluster-level and which are instance-level
parameters.

A few more hlint fixes

I'm ignoring the use of Control.Arrow.*** since it's a non-obvious
function, and we're not widely using Arrows in the code base, so I
think switching to it would make the code less readable to most
people.

Add many more opcode parameters

This is a bulk add of all node parameters needed for node and cluster
opcodes. The parameters are defined with a few helper functions in
this module, and, opposite from opcodes.py, there won't be any (new)
opcode attributes declared in-line (without a separate field...

Split OpCode.hs and add module for opcode parameters

Due to TemplateHaskell stage restrictions, we can't define parameters
in the same module as we're using them for TH, so we have to define
all module parameters in a separate module.

This patch therefore splits OpCodes.hs in two, adding that module and...
