What this PR does / why we need it:

DO NOT SUBMIT, NOT TESTED

This PR is a workaround for CVE-2019-3874. It disables the PCTP protocol on all nodes.

Which issue(s) this PR fixes:

Special notes for your reviewer:
This is not yet tested due to the lack of testing environment for Alicloud (or failure to set up a working environment). It was migrated from #33 which tested ok.

Release note:

The CoreOS Container Linux (Alicloud-modified) controller does now disable the PCTP protocol on all nodes (as a workaround for CVE-2019-3874).

@marwinski , I did a test with your configuration and sctp.conf is written successfully. Do we need a further test?
