Revert "added w:all GLEs after auth Tokutek/mongo#425"

This reverts commit 69d42368a60235e3c8af01af96fa0e7a79826d07.

This did not fix the problems with auth on mongos.
disabling auth over mongos tests Tokutek/mongo#425

These tests are flaky probably because of Tokutek/mongo#77
disabling a tailable cursor test on mongos Tokutek/mongo#424

Not really sure why this one fails, but it doesn't seem like a huge deal.
Maybe a weird interaction with sharding.
