The function call in to zebra_interface_nhg_reinstall
is an action that takes place on interface up events
*not* when the connected addresses are added to
a system. this will prevent this function being
called when new connected interfaces come alive
that is an independent operation of the interface
coming up.

When installing a NHG via dplane_nexthop_add, it can only return
REQUEST_QUEUED or REQUEST_FAILURE. There is no way SUCCESS can
be returned with the way the dplane works at this point in time.
Remove the code that attempts to set the NHE state appropriately
as it is impossible.

These commands don't really provide any functionality. VRF is associated
with netns automatically based on its name, and it's not possible to
associate VRF and netns with different names with these commands:
- When trying to assosiate a VRF with an already existing netns with a
different name:
`NS /run/netns/test is already configured with VRF 1(test)`
- When trying to assiciate a VRF with a non-existing netns, so they
become linked once the netns is created:
`Invalid pathname for /run/netns/test: No such file or directory`
- When doing "no netns" to unlink the netns and link it back to the same
VRF:
`VRF 1 is already configured with VRF test`
- When doing "no netns" to unlink the netns and link it to another VRF:
`Can not associate NS 4294967295 with NETNS /run/netns/test`
As shown above, not a single usecase is working. We can't remove them
completely to preserve backwards-compatibility, so just make them empty.
The main reason for this change is not to spend a lot of time trying to
figure out how to convert them to northbound.

Currently, when editing a leaf-list, `nb_candidate_edit` expects to
receive it's xpath without a predicate and the value in a separate
argument, and then creates the full xpath. This hack is complicated,
because it depends on the operation and on the caller being a backend or
not. Instead, let's require to always include the predicate in a
leaf-list xpath. Update all the usages in the code accordingly.
