Fix federation flaky tests

[nikhiljindal]

Filing this issue to keep track of fixing and reenabling flaky federation unit tests that were disabled in #36536.

Both @mwielgus and I are debugging.

This needs to be triaged as a release-blocker or not for 1.5 @nikhiljindal @mwielgus

[dims]

@nikhiljindal all issues must be labeled either release blocker or non release blocking by end of day 18 November 2016 PST. (or please move it to 1.6) cc @kubernetes/sig-cluster-federation

Not a v1.5 release blocker.

[ethernetdan]

Moving to 1.7 as late to happen in 1.6. Feel free to switch back if this is incorrect.

[marun]

Assuming this should not be blocking 1.7.

@nikhiljindal Can this issue be closed?

Fixed by #37307 and #37659
