tools: fix pim interface config deletionII
When no ip pim is performed subsequent pim related
configs under the interface also implicitly deleted.
The previous fix was attempting to remove from the same
list which was being integrated.
First collect the lines to remove in separate list
then at the end remove from the original lines_to_del.
commit 623af04e1c does not work properly if tries to delete
an entry from existing list which is being walked on.

lib, zebra: Check for not being a blackhole route
In zebra_interface_nhg_reinstall zebra is checking that the
nhg is a singleton and not a blackhole nhg. This was originally
done with checking that the nexthop is a NEXTHOP_TYPE_IFINDEX,
NEXTHOP_TYPE_IPV4_IFINDEX and NEXTHOP_TYPE_IPV6_IFINDEX. This
was excluding NEXTHOP_TYPE_IPV4 and NEXTHOP_TYPE_IPV6. These
were both possible to be received and maintained from the upper
level protocol for when a route is being recursively resolved.
If we have gotten to this point in zebra_interface_nhg_reinstall
the nexthop group has already been installed at least once
and we *know* that it is actually a valid nexthop. What the
test is really trying to do is ensure that we are not reinstalling
a blackhole nexthop group( Which is not possible to even be
here by the way, but safety first! ). So let's change
to test for that instead.

bgpd: fix addressing information of non established outgoing sessions
When trying to connect to a BGP peer that does not respons, the 'show
bgp neighbors' command does not give any indication on the local and
remote addresses used:
> # show bgp neighbors
> BGP neighbor is 192.0.2.150, remote AS 65500, local AS 65500, internal link
> Local Role: undefined
> Remote Role: undefined
> BGP version 4, remote router ID 0.0.0.0, local router ID 192.0.2.1
> BGP state = Connect
> [..]
> Connections established 0; dropped 0
> Last reset 00:00:04, Waiting for peer OPEN (n/a)
> Internal BGP neighbor may be up to 255 hops away.
> BGP Connect Retry Timer in Seconds: 120
> Next connect timer due in 117 seconds
> Read thread: off Write thread: off FD used: 27
The addressing information (address and port) are only available
when TCP session is established, whereas this information is present
at the system level:
Add the display for outgoing BGP session, as the information in
the getsockname() API provides information for connected streams.
When getpeername() API does not give any information, use the peer
configuration (destination port is encoded in peer->port).

`bgp graceful-restart` as an example:
Before:
```

Graceful restart configuration changed, reset all peers to take effect

After:
```
anlan(config-router)# bgp graceful-restart
Graceful restart configuration changed, reset all peers to take effect
anlan(config-router)# bgp graceful-restart
anlan(config-router)#
```
The same command should be accepted, it is an empty operation. Take
`neighbor <X> graceful-restart-helper` as an example:
Before:
```
anlan(config-router)# neighbor 3.3.3.3 graceful-restart-helper
Graceful restart configuration changed, reset this peer to take effect
anlan(config-router)# neighbor 3.3.3.3 graceful-restart-helper
Graceful restart configuration changed, reset this peer to take effect
% The Graceful Restart command used is not valid at this moment.
anlan(config-router)#
```
After:
```
anlan(config-router)# neighbor 3.3.3.3 graceful-restart-helper
Graceful restart configuration changed, reset this peer to take effect
anlan(config-router)# neighbor 3.3.3.3 graceful-restart-helper

needs to be installed into the evpn tables. Unfortunately
this function was walking the entirety of evpn tables
3 times. Modify the code to walk the tree 1 time and
to just look for the needed route types as you go.
