iallocator: fix incomplete refactoring

Commit fdbe29ee changed the iallocator modes from 'r'/'w' to
'ro'/'rw', but forgot one check in LUTestAllocator. This patch just
completes the replacements.

iallocator: export the hypervisor value

In 'allocate' mode, the documentation specifies that we export the
hypervisor value (“Allocation needs, in addition: … hypervisor, the
hypervisor of this instance”) and we need that on input, however we
don't actually export it....

iallocator: change default for target_groups

Per the design doc, the target_groups request key "if present, it must
either be the empty list, or contain a list of group UUIDs". Currently
it defaults to None/null, which is not valid.

iallocator: rename mem_size to memory

Currently, the iallocator in 'allocate' requires mem_size on input
but serialises that as 'memory'. This inconsistency makes it hard to
automatically validate the parameters, hence this patch renames
mem_size.

iallocator: add ht-checking for the request

Currently, we only ht-check the result value from the iallocator, and
we send whatever we happen to check manually in the LUs that call the
iallocator.

This is not good, as we have to duplicate checks in many places, and...

gnt-node migrate: Use LU-generated jobs

Until now LUNodeMigrate used multiple tasklets to evacuate all primary
instances on a node. In some cases it would acquire all node locks,
which isn't good on big clusters. With upcoming improvements to the LUs
for instance failover and migration, switching to separate jobs looks...

ht: Accept both int and long as integers

This fixes a unittest failure on 32 bit systems. A recently added
unittest for ht.TJobId uses a rather large number (2347625220). On 64
bit systems it is stored as “int”. On 32 bit systems however, Python
uses “long”. The two types can be intermixed in Python as the...

ht: Add checks for anything, regexp, job ID, container items

The check for container items is useful for tuples and/or lists with
non-uniform values. The “anything” check can be used when any value
should be accepted for an item.

The job ID check, which uses the regexp check, will be used for...
