[8u-dev] Request for approval for JDK-8151731: Add new jtreg keyword to jdk 8

[Svetlana Nikandrova]

Hello,

please approve 2 additional jtreg keywords used in jdk 9: "intermittent" 
and "randomness".
This test's marking can be useful by itself and will simplify tests' and 
test's fixes backporting.
