shill: Pass a parameter to dhcp client to request a hostname
This will enable dynamic DNS, or at the very least allow DHCP
requests to be identified and distinguished at the server side.
BUG=chromium-os:23741
TEST=New unit tests monitor hostname arg passed to dhcpcd,
and to assure values are being loaded/saved. Also double
checked on real system by doing a dbus-send to set manager.HostName
and checked that the name was persisted, and that the next
DHCP server we connected to stored this hostname.
