Rewrite plugin in Go - First RC

Release candidate - The following issues are still outstanding https://github.com/projectcalico/calico-cni/milestone/1

This release marks a complete rewrite of the Calico plugin in Go. This means fast startup times for better performance.

It adds the following features:

• Support for k8s username/password explicit config
• Performance

Notes

• The network plugin (calico) should be upgraded at the same time as the IPAM plugin (calico-ipam if used)
  • When using Calico for IPAM, the calico-ipam binary must be present. In the python version the functionality was also built into the calico plugin directly.
• Users shouldn't need to change network config and should be able to upgrade a running system.
• The format of the -v option to output the version has changed
• There is a new default for the k8s_api_root
• Support for the deprecated Kubernetes annotation based policy has been removed

For details of the configuration changes see the changes to configuration.md in the diff below.

Add kubeconfig, podCIDR support

• Adds the ability to use kubeconfig to access/authenticate with the Kubernetes API using the following CNI network config snippet:

"kubernetes": {
  "kubeconfig": "/path/to/kubeconfig"
}

• Also adds the ability to read podCIDR from the Kubernetes API to configure the subnet when using host-local IPAM.

"ipam": {
  "type": "host-local",
  "subnet": "usePodCidr"
}

Changes for Kubernetes v1alpha1 NetworkPolicy API

This release includes changes to support the Kubernetes v1alpha1 NetworkPolicy API in conjunction with the Calico Kubernetes policy agent.

Notably, this release changes the Calico workload_id and orchestrator when running under Kubernetes. This means that deployments using the v1.1 CNI plugin should not downgrade to v1.0 CNI plugin versions (though upgrade from v1.0 to v1.1 is supported).

This release also introduces the --version flag, which prints CNI plugin versioning information for both the calico and calico-ipam binaries.

Version v1.0.2

Version v1.0.2 of the calico-cni plugin adds better support for IPv6. In particular, it's now compatible with ipam plugins (such as host-local) which don't return IPv6 addresses.
