EC2: Fix bug using fallback_nic and metadata when restoring from cache.
If user upgraded to new cloud-init and attempted to run 'cloud-init init'
without rebooting, cloud-init restores the datasource object from pickle.
The older version pickled datasource object had no value for
_network_config or fallback_nic. This caused the Ec2 datasource to attempt
to reconfigure networking with a None fallback_nic. The pickled object
also cached an older version of ec2 metadata which didn't contain network
information.
This branch does two things:
- Add a fallback_interface property to DatasourceEC2 to support reading the
old .fallback_nic attribute if it was set. New versions will
call net.find_fallback_nic() if there has not been one found.
- Re-crawl metadata if we are on Ec2 and don't have a 'network' key in
metadata
