Hi folks

I'm working on host_route function on quantum.

https://bugs.launchpad.net/quantum/+bug/1022737
https://bugs.launchpad.net/quantum/+bug/1025817

Hopefully, I wanna take this bug also ( Actually fix is same for 1022737)
https://bugs.launchpad.net/quantum/+bug/1008180

By implement this bug, I'm start thinking that
DHCP option attribute is more general and natural rather than
host_route or dns_nameservers.

So here is proposal

/v2.0/subnets
    ...
    dhcp_options
{"option":"option:router",value:"10.0.0.1","option":"121","value":"10.0.100.0/24,10.0.100.1"
} #Default value of ports
    ...

/v2.0/ports
    ...
    dhcp_options
{"option":"option:router",value:"10.0.0.1","option":"121","value":"10.0.100.0/24,10.0.100.1"
} #Inherit from subnets
    ...

By this modification, we can support tons of DHCP options in quantum

Implementation would be more simple and generic.
( Actually, I can fix multiple bug by this change :) )

I'm very welcome to your comments.
