JDK11/8 Updates: process, schedules and tagging

[Lindenmaier, Goetz]

Hi,

> I do think "RDP2" should be avoided as there is no "RDP1".
I understand you don't want the OpenJDK RDP terms.
So let's use the term Rampdown.

Could you please propose some wording to describe which 
changes are acceptable during rampdown?

I will do the weekly tags on 11.

Best regards,
  Goetz.
