Introduce a wrapper for hostname resolving

Currently a few of the LU's CheckPrereq use utils.HostInfo which raises
a resolver error in case of failure. This is an exception from the
standard that CheckPrereq should raise an OpPrereqError if the error is
in the 'pre' phase (so that it can be retried)....

Introduce two-argument style for OpPrereqError

This patch introduces a two-argument style for OpPrereqError. Only the

Remove the OpRetryError exception

This is only used in two places, in an error path that is no longer
valid since Ganeti 2.0. We remove the try..except since we should not
get it anymore (and if we do, then we should catch it in all
config.Update cases) and we remove the exception class completely....

Move the luxi error handling into errors.py

Currently the luxi error handling is hardcoded as special encoding on
the masterd-side and special decoding on the client side. This patch
moves it to errors.py such that other parts of the code can reuse the
same encoding....

Conver node_leave_cluster rpc to new style result

changes in the process the meaning of the QuitGanetiException's
arguments and the node daemon rpc call exception handler.

Instance parameters: force typing

We want all the hv/be parameters to have a known type, rather than a
random mix of empty string, boolean values, and None, so we declare the
type of each variable and we enforce/convert it.

Add job queue size limit

A job queue with too many jobs can increase memory usage and/or make
the master daemon slow. The current limit is just an arbitrary number.
A "soft" limit for automatic job archival is prepared.
