Ignore InstanceNotFound while getting console output

During we cold-migrating or resizing an instance to another host,
or during deleting it, the get_console_output method may raise an
InstanceNotFound excetpion if the instance is not on the hypervisor,
this is an expected error, so we should add it to expected
exceptions list in compute manager.

remove unneeded call to network_api on rebuild_instance

When rebuilding an instance we call the network_api and which results in
calling neutron and updating the info cache. We do not actually need to
do this as we can get the nw_info directly from the instance's info cache.

Fix exception message being changed by nested exception

Minor change to avoid having the error message changed in the
_build_instance exception handler if an exception occurs during
network cleanup.

xenapi: make auto_config_disk persist boot flag

Currently auto_config_disk creates a new partition that ignores many
settings on the original partition.

The key flag that should be respected is the "boot" flag. When present
on the old partition, it should be present on the new partition.
