Andy Goldstein d2bc4d0b2e Use shared informers for proxy endpoints and service configs 
Use shared informers instead of creating local controllers/reflectors
for the proxy's endpoints and service configs. This allows downstream
integrators to pass in preexisting shared informers to save on memory &
cpu usage.

This also enables the cache mutation detector for kube-proxy for those
presubmit jobs that already turn it on.

Tim Hockin adf30aa2e1 kube-proxy: OnServiceUpdate takes pointers 
This signature is more consistent with OnEndpointsUpdate and removes a
copy loop.  This is part on ongoing cleanup to rate-limit iptables
calls.

Michael Taufen f5eed7e91d Add a separate flags struct for Kubelet flags 
Kubelet flags are not necessarily appropriate for the KubeletConfiguration
object. For example, this PR also removes HostnameOverride and NodeIP
from KubeletConfiguration. This is a preleminary step to enabling Nodes
to share configurations, as part of the dynamic Kubelet configuration
feature (#29459). Fields that must be unique for each node inhibit
sharing, because their values, by definition, cannot be shared.

Automatic merge from submit-queue

Allow multipe DNS servers as comma-seperated argument for kubelet --dns

This PR explores how kubectls "--dns" could be extended to specify multiple DNS servers for in-cluster PODs. Testing on the local libvirt-coreos cluster shows that multiple DNS server are injected without issues.

Specifying multiple DNS servers increases resilience against
- Packet drops
- Single server failure

I am debugging services that do 50+ DNS requests for a single incoming interactive request, thus highly increase the chance of a slowdown (+5s) due to a single packet drop. Switching to two DNS servers will reduce the impact of the issues (roughly +1s on glibc, 0s on musl, error-rate goes down to error-rate^2).

Note that there is no need to change any runtime related code as far as I know. In the case of "default" dns the /etc/resolv.conf is parsed and multiple DNS server are send to the backend anyway. This only adds the same capability for the clusterFirst case.

I've heard from @thockin that multiple DNS entries are somehow considered. I've no idea what was considered, though. This is what I would like to see for our production use, though.

Rene Treffer 42ff859c27 Allow multipe DNS servers as comma-seperated argument for --dns 
Depending on an exact cluster setup multiple dns may make sense.
Comma-seperated lists of DNS server are quite common as DNS servers
are always plain IPs.
