Not support set router admin down

[Na Zhu]

In neutron, when set the router admin down, the netns for the router is deleted.
But in OVN, there is no support about router admin state up/down.

We could implement this by deleting the router from OVN for now.

We implemented administrative port state in OVN for ports. I suppose we could do the same for routers.

Can you assign this bug to me, i think i can fix it.

[Na Zhu (nazhu)]

@Russel, there is column "enabled" in table Logical_Port, when set admin state down for neutron port, the plugin set the column "enabled" to false, not delete the logical port.

Since table Logical_Router does not have column "enabled", we can not do router admin state the same as port.
I think delete the router from OVN is a simple way.

[Russell Bryant (russellb)]

Yes, deleting the router is fine. That's the only way to do it today.

I'd also be happy with a patch to OVN adding an enabled flag to Logical_Router.

@Russell, I think add enabled flag to Logical_Router is a better, I will submit a patch for it.

    The ovn table logical_router has column 'enabled',
    when admin-state-up is true, set the column 'enabled' to true,
    when admin-state-up is false, set the column 'enabled' to false.
