bug 1344321 - remove linux64-pgo from target_tasks_mozilla_beta. r=dustin a=release MozReview-Commit-ID: AVai8RLFTVo

bug 1344321 - add nightly test support. r=dustin a=release this patch: - adds linux{32,64}-nightly/opt test platforms that mirror the non-nightly test platforms. - adds an `include_nightly` per-project parameter; this is refered to in the default `target_task_method`. It's still possible to launch custom `target_task_method`s to trigger nightlies against, say, try. - adds a `filter_for_project` method in `target_tasks.py` that allows for `include_nightly` and `run_on_projects` filtering in the various `target_task_method`s. - adds nightly filtering into the `TryOptionSyntax` object. By default, this will be off. To trigger nightly tests on try, either submit a new decision task with a different `target_task_method` (e.g. `nightly_fennec`) or flip the `include_nightly` flag to True. - adds the `nightly` attribute to tests if their builds have that attribute.
