Adds the option for GPU pixel tests to define a grace period, during which failures will not be surfaced on the waterfall bots. This is to help prevent newly added tests from turning the bots red due to a bunch of untriaged images showing up after a test is first added. The grace period gives the test author a bit of time to triage any new images before the test starts failing.
