The default lease acquisition timeout of 62 seconds is way too long when
running multiple testcases, overrunning the `go test` timeout of 10m. Let
testcases specify a shorter timeout.

Eventually the timeout value will become a CLI argument
The default timeout was nestled all the way in the lease constructor
This commit is the first step in making the timeout configurable by
moving it to the DHCPLease constructor

Values changed by Tuning plugin should be changed only for pod, therefore should be reverted when NIC is being moved from pod back to host.

Instead of checking the total number of addresses, which might vary
depending on the IPv6 Privacy Address settings of the distro being
used, just check that we have the number of non-link-local addresses
we expect.

conntrack does not have any way to track UDP connections, so
it relies on timers to delete a connection.
The problem is that UDP is connectionless, so a client will keep
sending traffic despite the server has gone, thus renewing the
conntrack entries.
Pods that use portmaps to expose UDP services need to flush the existing
conntrack entries on the port exposed when they are created,
otherwise conntrack will keep sending the traffic to the previous IP
until the connection age (the client stops sending traffic)

The e2e tests already covers both versions, and since the plugin is
meant to be used in chains, this will augment the scope of the plugins
it can be used with.

This plugin allows to create a VRF with the given name (or use the existing
one if any) in the target namespace, and to allocate the interface
to it.
VRFs make it possible to use multiple routing tables on the same namespace and
allows isolation among interfaces within the same namespace. On top of that, this
allow different interfaces to have overlapping CIDRs (or even addresses).
This is only useful in addition to other plugins.
The configuration is pretty simple and looks like:
{
"type": "vrf",
"vrfname": "blue"
}

This change allows providing an 'ipam' section as part of the
input network configuration for flannel. It is then used as
basis to construct the ipam parameters provided to the delegate.
All parameters from the input ipam are preserved except:
* 'subnet' which is set to the flannel host subnet
* 'routes' which is complemented by a route to the flannel
network.
One use case of this feature is to allow adding back the routes
to the cluster services and/or to the hosts (HostPort) when
using isDefaultGateway=false. In that case, the bridge plugin
does not install a default route and, as a result, only pod-to-pod
connectivity would be available.
Example:
{
"name": "cbr0",
"cniVersion": "0.3.1",
"type": "flannel",
"ipam": {
"routes": [
{
"dst": "192.168.242.0/24"
},
{
"dst": "10.96.0.0/12"
}
],
"unknown-param": "value"
},
"delegate": {
"hairpinMode": true,
"isDefaultGateway": false
}
...
}
This results in the following 'ipam' being provided to the delegate:
{
"routes" : [
{
"dst": "192.168.242.0/24"
},
{
"dst": "10.96.0.0/12"
},
{
"dst" : "10.1.0.0/16"
}
],
"subnet" : "10.1.17.0/24",
"type" : "host-local"
"unknown-param": "value"
}
where "10.1.0.0/16" is the flannel network and "10.1.17.0/24" is
the host flannel subnet.
Note that this also allows setting a different ipam 'type' than
"host-local".
