This rpc doesn't have explicit failure modes, but once all RPCs are
converted and we can catch and convert expceptions to failure in noded,
we will have meaningfull error messages.

In order to do that we change the way nics are espected to be passed to
the _BuildInstanceHookEnv function, from (ip, bridge, mac) to (ip, mac,
mode, link).

To translate new nics, which have the ip, mac and nicparams fields to
this new format we add an auxiliary _PreBuildNICHooksList function,
which is called both in _BuildInstanceHookEnvByObject and in
LUCreateInstance, where we don't have an Instance object created yet, at
hooks execution time.

LUSetInstanceParams hooks generation is also changed to provide the
right override to the nics field, should any nics be modified.

Rather than checking all bridges, we check all links for bridged nics,
if any. Since this function is now slightly more complex than before,
it's been split into an auxiliary function, and more parameters are
used, so that it can be called from more places, rather than
reimplementing the same code there.

This patch adds a simple failure reporting tool, similar to bdev's
_ThrowError. In backend, we move towards the new-style RPC results (of
type (status, payload)) and thus functions which use this style can very
easily log and return the error message using this new function.

The exception is declared here and not in errors.py since it's local to
the node-daemon/backend combination.

This also migrates the default bridge from the cluster object to the nic
