When a user specifies static routes, there are a couple of states
where we will store the route and display it as part of the 'show run'
but it will not be installed until such time that the dependant state
is created. Add some breadcrumbs to the user so that they can figure
out WTF just happened.

Holdem statics display the dest (and mask, if present) string that the
user entered instead of converting to CIDR notation and applying the
mask. They need to do the latter.

Prevent zebra from crashing for when the nexthop vrf has
changed in some manner and the lookup fails.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
When a user enables and disables a vrf, we were not
properly cleaning up the static routes leaving us
in a state where we would crash by looking at anything
in zebra.
On disable of a vrf -> Search through all static routes
and if the nexthop vrf is the disabled vrf uninstall it.
Additionally uninstall all static routes in that zvrf
On enable of a vrf -> Search through all static routes
and if the nexthop vrf is the enabled vrf install it.
Additionally install all the static routes in that zvrf.

This patch fixes two bugs with respect to static route configuration
inside vrf contexts:
* Entering a negative form of a static route created the static route.
* Once created, static routes could not be deleted.

If a user enters a route inside a non kernel existant vrf:

Currently if I try to use a nexthop-vrf that has

Add code to zebra so that if we fail to find the nexthop-vrf
we auto create it, instead of failing the install.

When zebra is being configed we allow for static routes
to be entered. This presents a problem for when a vrf
is cli configed but not kernel configed yet.
Modify zebra to notice that when a static route is
entered and either the nexthop vrf or the vrf
is not fully configed, to save that config to the
side.
When vrf's become active( kernel configed ) parse
through the list of saved to the side static routes
and determine if any of them can be installed.
Additionally modify the cli to output the saved
to the side cli, so that we can properly handle
a wr mem.

Show vrf command displays information on the vrf, if it is related to
vrf kernel or if it is related to netns.
When a vrf from kernel is detected, before creating a new vrf, a check
is done against an already present vrf, and if that vrf is not a vrf
mapped with a netns. If that is that case, then the creation is
rejected.

Asymmetric routing is an ideal choice when all VLANs are cfged on all leafs.
It simplifies the routing configuration and
eliminates potential need for advertising subnet routes.
However, we need to reach the Internet or global destinations
or to do subnet-based routing between PODs or DCs.
This requires EVPN type-5 routes but those routes require L3 VNI configuration.
This task is to support EVPN type-5 routes for prefix-based routing in
conjunction with asymmetric routing within the POD/DC.
It is done by providing an option to use the L3 VNI only for prefix routes,
so that type-2 routes (host routes) will only use the L2 VNI.

Refine the notion of what FRR considers as "configured" VRF. It is no longer
based on user just typing "vrf FOO" but when something is actually configured
against that VRF. Right now, in zebra, the only configuration against a VRF
are static IP routes and EVPN L3 VNI. Whenever a configuration is removed,
check and clear the "configured" flag if there is no other configuration for
this VRF. When user attempts to configure a static route and the VRF doesn't
exist, a VRF is created; the VRF is only active when also defined in the
kernel.

Testing Done:
1. Manual testing for L3 VNI and static routes - FRR restart, networking
restart etc.
2. 'vrf' smoke
<DETAILED DESCRIPTION (REPLACE)>
0. move all global EVPN details to 'show evpn [json]' command
1. change "VRF" to "Tenant VRF" in 'show evpn vni'
2. change 'show vrf vni' command to tabular form
and add l3-vni related params to the output
3. show evpn rmac should show refcount only in detailed output
4. show evpn next-hop should show refcount only in detailed output
5. move VRF in 'show evpn l3vni' to the end
6. add num rmacs and num nexthops to show evpn l3vni
7. remove "info" from 'show bgp vrf <> l3vni info'
8. show evpn vni <vni> should show l2vni details or l3 vni details
9. show evpn vni should show both L2 and L3 VNIs
10. show bgp l2vpn evpn - shows all global bgp l2vpn evpn details
11. show bgp l2vpn evpn vni - will show both l2 and l3 vnis
12. show bgp l2vpn evpn vni - should show both l2 and l3 vnis
