Because the backup nexthop groups currently are more like pseudo-NHEs
(they don't have IDs and are not inserted into the ID table or
hashed), they can't really have this depends/dependents relationship
yet in both directions. Some work needs to be done there to make
them more like first class citizens like "normal" NHGs to enable
this.

Instead of just counting the route suppressions, keep a reference for
all aggregations that are doing it. It should help the with the
following problems:
- Which aggregation suppressed the route.
- Double suppression
- Double unsuppression
- Avoids calling `bgp_process` if already suppressed/unsuppressed.
- Easier code maintenance and understanding
This also fixes a crash when modifying a route map that is
associated with a working aggregate-address.

Currently eigrp has a bunch of commands that are not fully
implemented yet. Tone down the yang code change of making
these in your face errors to zlog_warns, so the end-user
can not be freaked out by the message.

When `-r` is specified to zebra, on shutdown we should
not remove any routes from the fib. This was a problem
with nhg's on shutdown due to their ref-count behavior.
Introduce a methodology where on shutdown we don't mess
with the nexthop groups in the kernel. That way on
next startup things will be ok.

Remove py-ipaddr and ipsec-tools as deps in the Alpine build container,
as these were both Python 2 libraries and are not used here anymore
`ipsec-tools` is also no longer available in Alpine's test repos and was
causing breakage on this builder

Add test for new aggregate address option: test aggregate address option
without converged routes, then test again with a different route map
with converged routes.

Add new aggregate-address option to selectively suppress routes based
on route map results.

We currently have a global process queue for handling route
updates in bgp. This is fine, in general, except there are
places and times where we plug the queue for no new work
during certain peer states of bgp update delay. If we
happen to be processing multiple bgp instances on startup
why do we want to stop processing in vrf A when vrf B
is in a bit of a pickle?
Also this separation will allow us to start forward thinking
about how to fully integrate pthreads into route processing
in bgp.

The MH datastructures were being released before the paths that were
referencing them. Fix is to do the MH cleanup last.
The MH finish function has also been stripped down to only do a
datastructure cleanup i.e. avoid sending route updates etc.

Fix the following libyang error when trying to load the "frr-nexthop"
module explicitly (e.g. using the 'gen_northbound_callbacks' tool):

libyang: Invalid value "frr-nexthop-grouping" of "uses". (/frr-nexthop:frr-nexthop-group/frr-nexthop-grouping)
