ospf6d (and all other daemons except zebra) doesn't correctly process
`interface X vrf Y`, because it doesn't know existing VRFs at the time
of configuration file reading. Therefore it doesn't apply configuration
provided in the interface node.
Fix the problem by removing `vrf Y` part, having just an interface name
is enough.

To start we use 10k static route config. This test goes along with
recent batching changes it will fail w/o them (b/c some operations w/o
batching take 100 times as long).
This test should be added to over time for other large config
items (e.g., acl, policy, etc)

Test uses staticd which required some C++ header protections.
Additionally, the test also runs in the ubuntu20 docker container as
grpc is supported there by the packaging system.

similarly to what was done for IS-IS in commit 01d43141, combine
the SRGB and SRLB commands for OSPF-SR, so that we can replace
overlapping ranges in one sweep change.
Also allow the range configuration to be stored before SR is enabled.
There is no reason why we should not - in fact that constraint meant
that we were always requesting the default label ranges regardless
of what we actually wanted to use.
Finally, update the topotests now that we do not need to refresh
the SRGB/SRLB/MSD after disabling SR. Note that the prefix-sid still
needs to be re-added.

New OSPFv3 NSSA test:
* When a static route is redistributed to an NSSA router it should be
type 7 and should show up in OSPFv3 route database.
* Test LSA Type 7 and route removal.

As this comment says. ZEBRA_FLAG_XXX should not have been used.
To communicate SRv6 Route Information. A simple Nexthop Flag would
have been sufficient for SRv6 information. And I fixed the whole

The "show sharp segment-routing srv6" command was a
json output command, but it did not follow the common
practice of the other commands.
It follows the review and outputs the json format by
using the json keyword. Otherwise, it produces human

This commit is a part of #5853 works.
This commit add new topotest to verify SRv6-manager's functionality.
Following tests are performed on this topotest.
- check that SRv6-locator is set correctly
- check that default SRv6-function locator is set correctly
- check that SRv6-function is installed as ipv6 route correctly

This commit checks seg6local route configuration via ZAPI is
working fine.
SRv6 feature is little young feature as kernel feature so netlink
interface may be changed/updated in the future. And this ZAPI extention
is something to support new routing paradigm, so it should be checked by
topotests until srv6 feature of linux kernel will be well stable.

The backoff code assumed that yang operations always completed quickly.
It checked for > 100 YANG modeled commands happening in under 1 second
to enable batching. If 100 yang modeled commands always take longer than
1 second batching is never enabled. This is the exact opposite of what
we want to happen since batching speeds the operations up.
Here are the results for libyang2 code without and with batching.
| action | 1K rts | 2K rts | 1K rts | 2K rts | 20k rts |
| | nobatch | nobatch | batch | batch | batch |
| Add IPv4 | .881 | 1.28 | .703 | 1.04 | 8.16 |
| Add Same IPv4 | 28.7 | 113 | .590 | .860 | 6.09 |
| Rem 1/2 IPv4 | .376 | .442 | .379 | .435 | 1.44 |
| Add Same IPv4 | 28.7 | 113 | .576 | .841 | 6.02 |
| Rem All IPv4 | 17.4 | 71.8 | .559 | .813 | 5.57 |
(IPv6 numbers are basically the same as iPv4, a couple percent slower)
Clearly we need this. Please note the growth (1K to 2K) w/o batching is
non-linear and 100 times slower than batched.
Notes on code: The use of the new `nb_cli_apply_changes_clear_pending`
is to commit any pending changes (including the current one). This is
done when the code would not correctly handle a single diff that
included the current changes with possible following changes. For
example, a "no" command followed by a new value to replace it would be
merged into a change, and the code would not deal well with that. A good
example of this is BGP neighbor peer-group changing. The other use is
after entering a router level (e.g., "router bgp") where the follow-on
command handlers expect that router object to now exists. The code
eventually needs to be cleaned up to not fail in these cases, but that
is for future NB cleanup.

There are two possible use-cases for the `vrf_bind` function:
- bind socket to an interface in a vrf
- bind socket to a vrf device
For the former case, there's one problem - success is returned when the
interface is not found. In that case, the socket is left unbound without
throwing an error.
For the latter case, there are multiple possible problems:
- If the name is not set, then the socket is left unbound (zebra, vrrp).
- If the name is "default" and there's an interface with that name in the
default VRF, then the socket is bound to that interface.
- In most daemons, if the router is configured before the VRF is actually
created, we're trying to open and bind the socket right after the
daemon receives a VRF registration from zebra. We may not receive the
VRF-interface registration from zebra yet at that point. Therefore,
`if_lookup_by_name` fails, and the socket is left unbound.
This commit fixes all the issues and updates the function description.
