Subject: Add support for a DHCP_OPTS parameter.
This commit allows an interface specific DHCP_OPTS parameter to set
additional dhcpcd command line options where they may be required
on a local network. It is still recommended to use the supported
DHCP_* options in preference to this option, but it is being added
to aid customisations.
Thanks to ljb643 on LQ for the bug report regarding DHCP_IPADDR
and the suggestion of a DHCP_OPTS parameter.
