sysconfig/network: NO_DHCP_HOSTNAME option introduced
Previously, some administrators were unable to force initscripts to
not obtatin hostname from DHCP, even though they were using static
configuration of network. Righ now, setting 'NO_DHCP_HOSTNAME' to
'yes', 'true' or '1' in /etc/sysconfig/network will allow them to do so.
