LUXI queries are processed without callbacks (see
server.masterd.ClientOps._Query). With commit 07923a3c the logic for
checking an opcode's result for jobs to submit was changed and
subsequently raised an exception (“'NoneType' object has no attribute
'SubmitManyJobs'”) in such a case. Before said commit the exception
would also have been raised if an opcode used by a query submitted jobs.

This patch changes the logic to only resolve the method if callbacks are
defined and to use an exception-raising implementation otherwise.

(cherry picked from commit 54b010ca)

Commit 3b3b1bca does not entirely fix the bug introduced in commit
f396ad8c. It fixes consistency of config data in permanent storage, but
does not ensure consistency in data held in runtime memory of masterd.

The bug of duplicate ports is still triggered when LUInstanceRemove()
invokes _RemoveDisks() and this returns False (in case
call_blockdev_remove RPC fails). The drbd ports get returned in the
pool, but execution is aborted and RemoveInstance() is never invoked.

Due to the fact that port handling is not done with
TemporaryReservationManager, ensure that ports are released, only if
disk related config data is deleted.

In _RemoveDisks() release ports only if all RPCs succeed.

Extend _RemoveDisks() to include ignore_failures argument passed by
_RemoveInstance() to handle the ports appropriately.

Commit f396ad8c returns the TCP port used by DRBD disk back to the
TCP/UDP port pool using AddTcpUdpPort().

However, AddTcpUdpPort() writes the config on every invocation,
using _WriteConfig(). This causes two problems:

 * it causes critical errors logged by VerifyConfig(), after the DRBD
   disk removal, and until the actual instance removal.
 * if the code following AddTcpUdpPort() fails, the port is already
   returned back the pool, which causes the port to have duplicates
   (inconsistent config).

AddTcpUdpPort() is invoked in three cases:

 * during InstanceRemove() through _RemoveDisks().
 * during InstanceSetParams() in case of disk removal.
 * during InstanceSetParams() through _ConvertDrbdToPlain().

This commit fixes the problem by removing the _WriteConfig() call from
AddTcpUdpPort(), delegate it to Update() via the
TemporaryReservationManager and ensure AddTcpUdpPort() precedes
Update().

This patch moves the “call_version” to a new RPC client definition and
then adds a new runner using the DNS resolver for getting the host

The standard “BootstrapRunner”, where the call was before, tries to
resolve node names using ssconf first, which doesn't work properly when
re-adding a node with a new primary IP address.
