GitHub Actions recently updated ubuntu-latest to 22.04 [1], which now
defaults to nfttables (rather than iptables-legacy) [2]. The portmap
tests in this project are written with the expectation that expected
error message for one test is in the iptables-legacy format.
This commit updates the check to make it work for both the
iptables-legecy and iptables-nftables variants.

This commit changes the order of substituting sysctl path to first handle
. to / change, before substituting the interface name.
This is needed as vlan interfaces have a . in the name, which should not
be changed.

checkPorts would return nil rather than an error if the per-container
DNAT chain didn't exist, meaning CHECK would erroneously return
success rather than failure.
chain.check() already (correctly) checks that the chain exists, so
there's no need to do it separately before calling that anyway.

This commit adds a new parameter `ingressPolicy` (`string`) to the `firewall` plugin.
The supported values are `open` and `same-bridge`.
- `open` is the default and does NOP.
- `same-bridge` creates "CNI-ISOLATION-STAGE-1" and "CNI-ISOLATION-STAGE-2"
that are similar to Docker libnetwork's "DOCKER-ISOLATION-STAGE-1" and
"DOCKER-ISOLATION-STAGE-2" rules.
e.g., when `ns1` and `ns2` are connected to bridge `cni1`, and `ns3` is
connected to bridge `cni2`, the `same-bridge` ingress policy disallows
communications between `ns1` and `ns3`, while allowing communications
between `ns1` and `ns2`.
Please refer to the comment lines in `ingresspolicy.go` for the actual iptables rules.
The `same-bridge` ingress policy is expected to be used in conjunction
with `bridge` plugin. May not work as expected with other "main" plugins.
It should be also noted that the `same-bridge` ingress policy executes
raw `iptables` commands directly, even when the `backend` is set to `firewalld`.
We could potentially use the "direct" API of firewalld [1] to execute
iptables via firewalld, but it doesn't seem to have a clear benefit over just directly
executing raw iptables commands.
(Anyway, we have been already executing raw iptables commands in the `portmap` plugin)

This commit replaces the `isolation` plugin proposal (issue 573, PR 574).
The design of `ingressPolicy` was discussed in the comments of the withdrawn PR 574 ,
but `same-network` was renamed to `same-bridge` then.

Since the CNI Spec bump to v1.0 the tuning plugin no longer updates the
mac address in the cni result for 0.4.0 or below configs. I don't think
this ever worked when the cni result was converted to a different version.
A test has been added to ensure it is working for all spec versions.

This adds support to allow the tuning plugin to enable/disable the
allmulticast mode of the interface. When enabled it instructs the
network driver to retrieve all multicast packets from the network.
