The `bgp no-rib` command cycles through all the bgp rib tables
and removes them from zebra. Modify the code so that FRR notices
that it is attempting to cycle through the safi's that are two level
tables. In addition these safi's cannot just blindly remove the routes
from the rib as that there are none explicitly.
This code just prevents the crash in bgpd. It does not properly cycle
through and remove the zebra changes made that are explicit to these afi's.
This should be handled as appropriate by the developers on these safi's when
it becomes important to them.

Problem Statement:
=================
PIM Logs are coming at interval of 1 minute although pim
is not enabled.
Root Cause Analysis:
====================
By default, RCPM configures the PIM debugs when router comes up
via script. The product cannot disable PIM even though it is not required.
Hence moving these logs under a new debug option which will not be
enabled by default.
Fix:
====
Added a new option "detail" in the cli:
debug pim nht detail

Here "new" is very puzzling. If new parameters with default values on peer

So just clarify it:
Only "non-default" values on peer configuration node are set, they can override

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.
