Dan Williams aad6535a00 kubenet: fix up CNI bridge TX queue length if needed 
CNI's bridge plugin mis-handles the TxQLen when creating the bridge,
leading to a zero-length TX queue.  This doesn't typically cause
problems (since virtual interfaces don't have hard queue limits)
but when adding traffic shaping, some qdiscs pull their packet
limits from the TX queue length, leading to a packet limit of 0
in some cases.  Until we can depend on a new enough version of
CNI, fix up the TX queue length internally.

Arvinderpal dede4d507c Sets IgnoreUnknown=1 in CNI_ARGS 
K8 uses CNI_ARGS to pass pod namespace, name and infra container
id to the CNI network plugin. CNI logic will throw an error
if these args are not known to it, unless the user specifies
IgnoreUnknown as part of CNI_ARGS. This PR sets IgnoreUnknown=1
to prevent the CNI logic from erroring and blocking pod setup.

kubenet: Load bridge netfilter module in Init().

This lets the kubenet loads the bridge netfilter module and set bridge-nf-call-iptables=1

Fix #24018 

Follow up PRs would be appreciate if we also load the module in the bridge plugin binary itself. Ref https://github.com/kubernetes/kubernetes/issues/24018#issuecomment-207682514

handles shaping through OVS, but this triggers a warning when
kubelet notices the bandwidth annotations.

Dan Williams 6248939e11 Push responsibility for bridge-nf-call-iptables to kubelet network plugins 
bridge-nf-call-iptables appears to only be relevant when the containers are
attached to a Linux bridge, which is usually the case with default Kubernetes
setups, docker, and flannel.  That ensures that the container traffic is
actually subject to the iptables rules since it traverses a Linux bridge
and bridged traffic is only subject to iptables when bridge-nf-call-iptables=1.

But with other networking solutions (like openshift-sdn) that don't use Linux
bridges, bridge-nf-call-iptables may not be not relevant, because iptables is
invoked at other points not involving a Linux bridge.

The decision to set bridge-nf-call-iptables should be influenced by networking
plugins, so push the responsiblity out to them.  If no network plugin is
specified, fall back to the existing bridge-nf-call-iptables=1 behavior.

Tim St. Clair a263c77b65 Refactor liveness probing 
This commit builds on previous work and creates an independent
worker for every liveness probe. Liveness probes behave largely the same
as readiness probes, so much of the code is shared by introducing a
probeType paramater to distinguish the type when it matters. The
circular dependency between the runtime and the prober is broken by
exposing a shared liveness ResultsManager, owned by the
kubelet. Finally, an Updates channel is introduced to the ResultsManager
so the kubelet can react to unhealthy containers immediately.
