Merge lp:~darkmuggle-deactivatedaccount/ubuntu/precise/walinuxagent/lp1077148 into lp:ubuntu/precise-proposed/walinuxagent

[Ben Howard]

This package fixes the following issues:
    - Added - load ata_piix.ko module loaded if needed for CDROM device support
    - Additional logging for DoDhcpWork()
    - Update sock.recv timeout from 30 to 10 seconds
    - Fix: Linux waagent deprovision, user is not deleted properly
    - Fix: Make LBProbeResponder construction more robust
    - Fix: Agent fails to provision user with public/private key pairs
    - Fix: DHCP broadcast response not received
    - Fix: Linux agent fails to delete root user password
    - Fix: Linux agent should report error messages to Fabric when
           passed an invalid hostname.
