This prevents DHCP requests failures taking time during
boot if the interface isn't up yet. If the interface is
down, dhclient will fail to send packets.
At boot-time, enslaving an interface to vrf flaps it. By
waiting for the interface to come back up before starting
dhclient reduces time to boot.

Add a ifupdown2 policy attribute dhcp6-duid to allow user to specify the DUID type
to be used on an IPv6 enabled interface.

It is available since Kernel 4.19 and has two parmeters:
1. XFRM ID to map to an SA/SAs
2. Underlying Interface if you want to take advantage of IPSec Hardware Offload
Otherwise it is treated as a normal interface and not like a tunnel (VTI).
I added two attributes to the interface to configure it and otherwise use it as a normal interface.
One example is:
auto ipsec1
iface ipsec1 inet
xfrm-physdev lo
xfrmid 1
This fix this kind of error:
error: bond0: cmd '/sbin/sysctl net.bridge.bridge-stp-user-space' failed: returned 255 (sysctl: cannot stat /proc/sys/net/bridge/bridge-stp-user-space: No such file or directory

)
On ifreload (down ops) we need to purge the cache entry of the bridge and its upper devices
to avoid stale values in our cache.
ifup this config, then remove bridge-vids 20, ifreload: since the bridge is removed because
of ifreload_down_changed=1, we need torecreate the vlan bridge.10 and it's configuration, the
cache is stale. We need to clear it to remove the ip 10.10.10.10/32.

mstpctl might return an empty result on: mstpctl showportdetail bridge json
the cache is not filled with an empty dict so next cache lookup will be a
cache miss and therefore, ifupdown2 thinks we need to fill the cache with fresh
data and will execute showportdetail again (resulting in calling mstpctl cmd
sometime 5 or 6 times in a row).

When setting addrgenmode it is necessary to flap the macvlan
device. After flapping the device we also need to re-add all
the user configuration. The best way to add the user config
is to flush our internal address cache.

This commit adds support to configure and check gretap tunnels. An example
configuration could look like this:
iface tap0 inet tunnel
mode gretap
local 10.132.255.3
endpoint 10.132.255.1
ttl 64
mtu 1400
tunnel-physdev eth0
#
address 10.10.0.1/2
ifup will happily configure the interface (which it does even without this
patch) and ifquery now can successfully validate the configure interface:
cr03.in.ffho.net:~# ifquery -c tap0
iface tap0 inet tunnel [[ OK ]]
tunnel-physdev eth0 [[ OK ]]
endpoint 10.132.255.1 [[ OK ]]
local 10.132.255.3 [[ OK ]]
mode gretap [[ OK ]]
ttl 64 [[ OK ]]
mtu 1400 [[ OK ]]
address 10.10.0.1/24 [[ OK ]]

This commit adds support for configuring GRE/IPIP/SIT tunnel interfaces as know
from previous versions of ifupdown. Currently only configuration checks for GRE
and SIT tunnels are implemented.
A tunnel interface configuration could look like this:
auto gre42
iface gre42 inet tunnel
mode gre
local 198.51.100.1
endpoint 203.0.113.2
#
# optional tunnel attributes
ttl 64
mtu 1400
tunnel-physdev eth0
#
address 192.0.2.42/31
address 2001:db8:d0c:23::42/64
auto he-ipv6
iface he-ipv6 inet tunnel
mode sit
endpoint 203.0.113.6
local 198.51.100.66
#
# optional tunnel attributes
ttl 255
mtu 1466
tunnel-physdev vrf_external
#
address 2001:db8:666::2/64

This is a major update coming all at once from master-next branch
master-next branch was started with --orphan option which is basically a new
branch without history.
The major changes are:
- repackaging
- cleanup the directory tree
- rewritte setup.py to allow install from deb file or pypi (pip install)
- add a Makefile to make things (like building a deb) easier
- review all debian files
