Bug description:
  ---- Begin SRU Template ----
  [Impact] 
  Please see individual bugs listed for impact.  Some significant fixes added here are:
   - user_data: fix error when user-data is not utf-8 decodable (LP: #1532072)
   - support networking information being read from dreamcompute and older 
     versions of openstack.
   - support reading and applying networking information on SmartOS virtual
     machine guests.
   - fix reading networking from openstack network_data.json
   - support for renaming devices in a container (LP: #1579130).
   - remove blocking of udev rules (LP: #1577844, LP: #1571761)
   - Apt sources configuration improvements (LP: #1574113)
   - cloud-config specified on kernel command line will now override
     system settings (LP: #1582323).
   - Paths: fix instance path if datasource's id has a '/'. (LP: #1575938)
   - Config Drive: fix check_instance_id signature. (LP: #1575055)

  [Test Case]
  Most of the changes here are related to data provided by the cloud and properly configuring an instance in response to that data.

  Platforms:
   Azure
   NoCloud with network_config
   NoCloud without network_config
   Google GCE
   Openstack Config Drive
   Openstack Metadata Service
   LXD
   Joyent
   Dreamcompute
   MAAS (ephemeral env and installed environment)

  For each of these platforms, the following should be done once with user-data provided and once without.
   - Boot the latest available xenial instance (1 with user-data, 1 without)
   - Enable proposed and upgrade
   - save original /var/log/cloud-init.log and /var/log/cloud-init-output.log
   - reboot, check /var/log/cloud-init.log for WARN
     this checks that the upgrade from a previous version did not recognize any
     failures.
   - clean the instance to make it seem as much as possible like a first boot.
     ( cd /var/lib/cloud && for d in *; do [ "$d" = "seed" ] || rm -Rf "$d"; done )
   - reboot, check /var/log/cloud-init.log for WARN
     this mimics first boot in as close to a real scenario as possible without generating new images with the patched cloud-init.
   - reboot again, check /var/log/cloud-init.log for WARN
     this time check for second-boot issues.

  [Regression Potential] 
  The changes here that are most likely to cause regression are those related to network configuration.  cloud-init is now doing a better job of configuring the sytem as the datasource indicated it should be configured.  That could, however, have fallout network would be configured differently than before.

  [Other Info]
  This does represent significant changes.  Cloud-init is stabalizing toward a 0.7.8 release, and it is important to get these changes out.  They are present in yakkety, and available in a daily ppa at https://code.launchpad.net/~cloud-init-dev/+archive/ubuntu/daily , but being present exposes the new code to many more users.

  ---- End SRU Template ----

  
  There are several fixes in the current yaketty version of cloud-init that need to make it back to 16.04.  These are both bug fixes and more general improvements in code.

  This bug is a 'SRU metabug' to cover that SRU.  Below is a changelog
  format with individual bugs listed.  The uploaded version will have
  the bug references removed, but I will mark bugs individually as fix-
  released and reference this bug.
