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The design of `ingressPolicy` was discussed in the comments of the withdrawn PR 574 ,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.
