"Fix" handling of old software versions on startup

Currently, masterd startup with old software versions is very confusing

Remove errors.ConfdFatalError

This exception is caught, but never thrown. It became useless when we
moved confd from on/off to enabled/disabled, but always running on all
nodes. Removing its definition and the code catching it can do no harm.

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)....

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This is only used in two places, in an error path that is no longer
valid since Ganeti 2.0.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....

This exception does not signal an error but serves the purpose of making
