Imported using git-ubuntu import.

Changelog parent: d064ab0bffd429382ea4fafeb144784d403848bd

New changelog entries:
  * New upstream release (LP: #1661750).
  * debian/control:
    - Change the maintainer to Ubuntu Developers (LP: #1657528).
    - Add the dependency of isc-dhcp-client as our maintainer scripts assume
      it's installed.
    - Add trailing commas to dependencies, add whitespaces.
  * Rename ephemeral-disk-warning.sh to ephemeral-disk-warning (lintian error).
  * debian/docs:
    - Remove LICENSE.txt as it's redundant.
  * debian/postinst:
    - Stop checking for update-initramfs existence using the absolute path, use
      the 'command' command instead to make lintian happy.
  * Remove debian/patches/disable-auto-update.patch:
    - We now ship with auto-updates enabled (LP: #1650522).
  * debian/maintscript:
    - Add a maintscript to rename the old logrotate file on upgrade from an
      ancient version of walinuxagent (LP: #1673152).
