2 things:
a) Each test was setting up for graceful restart with calls to
`graceful-restart prepare ip[v6] ospf`, then sleeping for
3 or 5 seconds. Then killing the ospf process. Under heavy
load there is no guarantee that zebra has received/processed
this signal. Write some code to ensure that this happens
b) Tests are issuing commands in this order:
1) issue gr prepare command
2) kill router
3) <ensure routes were still installed in zebra>
4) start router
5) <ensure routes were stil installed in zebra>
Imagine that the system is under some load and there is
a small amount of time before step 5 happens. In this
case ospf could have come up and started neighbor relations
and also started installing routes. If zebra receives
a new route before step 5 is issued then the route could
be in a state where it is not installed, because it is
being sent to the kernel for installation. This would
fail the test because it would only look 1 time. This
is fixed by giving time on restart for the routes to
be in the installed state.

RFC 3623 says:
"If the restarting router determines that it was the Designated
Router on a given segment prior to the restart, it elects
itself as the Designated Router again. The restarting router
knows that it was the Designated Router if, while the
associated interface is in Waiting state, a Hello packet is
received from a neighbor listing the router as the Designated
Router".
Implement that logic when processing Hello messages to ensure DR
interfaces will preserve their DR status across a graceful restart.

We should never pass pointers to local variables to thread_add_* family.
When an event is executed, the library writes into this pointer, which
means it writes into some random memory on a stack.

Issue:
===================
OSPF neighbors are not going down even after 10 mins when
having a mismatch in hello and dead interval.
First neighbors are formed and then a mismatch in the interval
is created, it is observed that the neighbor is not going down.
Root Cause Analysis:
====================
The event HelloReceived defined in RFC 2328 was named as PacketReceived
and this event was scheduled whenever LS Update, LS Ack, LS Request,
DD description packet or Hello packet is received.
Although there is a mismatch in the Hello packet contents, the
event PacketReceived gets triggered due to LS Update received and the
dead timer gets reset and hence the neighbor was never going Down and
remains FULL.
Fix:
==================
As per RFC 2328, the HelloReceived needs to be triggered only when
valid OSPF Hello packet is received and not when other OSPF packets
are received. Modified the function name as well.

Since watchfrr invokes vtysh to gather the show run output and
write the data, if we are operating inside of a namespace FRR
must also pass this in.
Yes. This seems hacky. I don't fully understand why vtysh
is invoked this way.

The current code passes an address of a local variable to `thread_add_read`
which stores it into `thread->ref` by the lib. The next time the thread
callback is executed, the lib stores NULL into the `thread->ref` which
means it writes into some random memory on the stack.
To fix this, we should pass a pointer to the vector entry to the lib.

In startup, zebra would dump interface information from Kernel in 3
steps w/o lock: step1, get interface information; step2, get interface
ipv4 address; step3, get interface ipv6 address.
If any interface gets added after step1, but before step2/3, zebra
would get extra interface addresses in step2/3 that has not been added
into zebra in step1. Returning error in the referenced interface lookup
would cause the startup interface retrieval to be incomplete.
