fcf17cc05d doc: Add doc for show segment-routing srv6 manager 
The `show segment-routing srv6 manager` CLI command allows users to
print the SRv6 information. Currently, the SRv6 information includes
only the SRv6 encapsulation source address.

In this commit, we add the documentation for the
`show segment-routing srv6` command.

62196fbd19 zebra: Enable nht resolve-via-default by default for traditional profile 
Lots of questions raising regarding unresolved nht, I think it's time to
relax this and make it a default ON.

Here is an example list of issues when `nht resolvia-via-default` solved
the problem:

https://github.com/FRRouting/frr/issues/3241
https://github.com/FRRouting/frr/issues/7420
https://github.com/FRRouting/frr/issues/3474
https://github.com/FRRouting/frr/issues/5023
https://github.com/FRRouting/frr/issues/6504

https://github.com/FRRouting/frr/issues/7999
https://github.com/FRRouting/frr/issues/13215
https://github.com/FRRouting/frr/issues/14098

TL;DR;

The BGP session does not come up if using multihop sessions and/or the peer(nexthop)
is not accessible from the RIB, but only via default route. This is even valid for
iBGP, and not only for eBGP peering. Adding a static /32, /128 route for the peer
would do the trick, but it's a workaround.

If the route has a nexthop marked as invalid, most likely this is due to it can't
be resolved from the current RIB, but only via default route.

For instance, Cisco allows this by default (can't find even a knob to turn it
off or I'm blind).

For eBGP sessions it might be also combined with `disable-ebgp-connected-route-check`.

Some people asked if this could be a default, also for instance MetalLB is adding
this by default for all the configs it generates.

439d4c9b03 doc: Add documentation for behavior usid command 
Add the documentation for the `behavior usid` command to zebra.

When the `behavior usid` command is set, a flag is added to the locator
to indicate that the locator is a uSID locator. When a locator is
specified as a uSID locator, the bgpd will install SRv6 behaviors with
the uSID in the dataplane and use the SRv6 uSID codepoints in the BGP
update message.

ac2cb9bf94 *: rework renaming the default VRF 
Currently, it is possible to rename the default VRF either by passing
`-o` option to zebra or by creating a file in `/var/run/netns` and
binding it to `/proc/self/ns/net`.

In both cases, only zebra knows about the rename and other daemons learn
about it only after they connect to zebra. This is a problem, because
daemons may read their config before they connect to zebra. To handle
this rename after the config is read, we have some special code in every
single daemon, which is not very bad but not desirable in my opinion.
But things are getting worse when we need to handle this in northbound
layer as we have to manually rewrite the config nodes. This approach is
already hacky, but still works as every daemon handles its own NB
structures. But it is completely incompatible with the central
management daemon architecture we are aiming for, as mgmtd doesn't even
have a connection with zebra to learn from it. And it shouldn't have it,
because operational state changes should never affect configuration.

To solve the problem and simplify the code, I propose to expand the `-o`
option to all daemons. By using the startup option, we let daemons know
about the rename before they read their configs so we don't need any
special code to deal with it. There's an easy way to pass the option to
all daemons by using `frr_global_options` variable.

Unfortunately, the second way of renaming by creating a file in
`/var/run/netns` is incompatible with the new mgmtd architecture.
Theoretically, we could force daemons to read their configs only after
they connect to zebra, but it means adding even more code to handle a
very specific use-case. And anyway this won't work for mgmtd as it
doesn't have a connection with zebra. So I had to remove this option.
