  1. K8s SCTP support implementation for the first pull request 

    The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.

SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.

SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter

changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.

netexec.go compilation fixed. Various test cases fixed

SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)

SCTP related e2e test cases are removed as the e2e test systems do not support SCTP

sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go

cluster/gce/util.sh is copied from master
