zebra: Add one-shot thread to recheck speed
There are certain interfaces that when brought up and we receive
the netlink notification about it, the speed of the interface is
not set correctly. This creates a one-shot thread that will
wait 15 seconds and then requery the speed and if it is different
it will renotify the running daemons.
The kernel should notify us on speed changes, unfortunately this
is not done currently via a netlink message as you would think.
As I understand it there is some in-fighting about the proper
way to approach this issue and due to the way the kernel release
cycle works we are a ways off from getting this fixed. This
is a `hack` to make us work correctly while we wait for the
true answer.

bgpd: fix updating redist bitmask when vrf_id changes
Problem reported that when "systemctl restart networking" was
performed, prefixes previously redistributed into bgp from connected
were deleted from the bgp table. Determined that we were not correctly
changing the redistribution bitmask when the vrf_id of the vrf was
changed. This patch corrects that behavior.
Manual tests look good. bgp-min and vrf-min completed with no new failures.
