Currently the iallocator option is ignored by burnin at import/export
time even if passed in. With this patch it becomes used. The log message
used by the importer is also changed to reflect this.

This patch also improves import/export on the non-iallocator case:
  - The secondary node is not passed anymore on non-mirrored templates
  - On mirrored templates the secondary node is logged

There is a mistake in the error message generated when we can't reach a
node for checking for available disk space. Without it, the error
message is:
Failure: prerequisites not met for this operation:
Cannot get current information from node '{u'gnte2.lab.k1024.org':
{'cpu_total': 1, 'memory_free': 480, 'vg_size': 131068, 'memory_total':

instead of the expected:

When a Job raises a ganeti exception a message is printed but nothing is
reported in the job itself. It's better to update the job status, thus
notifying the client, possibly polling for the job result, of what went
wrong.

The remote API will use JSON for the foreseable future, so it's better
to put the serialization format in the function name. We can still

Currently the check for enough memory is done only on instance start
command and failover command. But we also start an instance in instance
create, therefore we need to check this instead of failing to start in
the hypervisor phase.

The patch adds a check for node memory in the case the creation command
specifies that the instance should be started. It is allowed for the
memory to be less than needed if the instance will not be started, in
order to allow migration and other such cases.

Currently: the LURemoveInstance.Exec() method uses the ignore_failures
attribute of the OpRemoveInstance opcode, but it doesn't check for its
existence. The patch adds this attribute to _OP_REQP and to all the
places where this opcode was created.

This attributes is always passed by gnt-instance, but burnin didn't pass
it so it can fail if it enters the 'fail to remove disks' branch of the
method (which is why it was not triggered until now).

It turns out in some cases there can exist keywords without an
associated value exported by drbdsetup show. This patch makes the value
part optional in our parser, so that if it's not present the parsing
result will contain an array with just the keyword in it. This is not a
problem since we check all keyword names before accessing their values,
so we won't mistakenly try to access the value of a valueless keyword.
