Message: OVN: Vlan backed DVR N-S, redirect-type option

Background:
With c0974331b7a19a87ab8f1f2cec8fbe366af92fa2, we have added
support for E-W workflow for vlan backed DVRs.

This series enables N-S workflow for vlan backed DVRs.

Key difference between E-W and N-S traffic flow is that
N-S flow requires a gateway chassis. A gateway chassis
will be respondible for following:
a. Doing Network Address Translation (NAT).
b. Becoming entry and exit point for North->South
   and South->North traffic respectively.

OVN by default always uses overlay encapsulation to redirect
the packet to gateway chassis. This series will enable
the redirection to gateway chassis in the absence of encapsulation.

This patch:
a. Add a new key-value in options of a router port.
b. This new config key will be used by ovn-controller
   to determine if a redirected packet will go out of
   tunnel port or localnet port.
c. key is "redirect-type" and it takes "overlay" and
   "vlan" as values.
d. Added ovn-nbctl command to set and get redirect-type
   option on a router port.
e. This new configuration is added because vlan or overlay
   based forwarding is considered to be a logical switch property,
   hence for a router configuration has to be done at the router port
   level.
f. Restored the function ovsdb_datum_to_smap, which helps in ensuring
   that we do not overwrite existing options, while adding a new
   key-value pair to it. This function exists in 2.8.5, i am not
   able to figure out so far, which release/why it was removed.
   I do not see a harm in adding it back.
