* use yaml 1.2 everywhere
This commit:
* gets rid of pyyaml
* uses ruamel everywhere
* tries to unite toml and yaml
However, this will require a few more changes that will come soonish.
Eg: Current `parse_yaml` and `parse_toml` behavior could be error-prone,
so, it's better to introduce `tree` inside these serialization methods
(which I will try to tackle next).
Another is, yaml load can be slow for json. We could speed it up just by
using `json.load(s)` here (also in upcoming patch).
* Fix tests
* dump: lockfile is dumped deterministically
The dump is no longer deterministic/dependent on the pipeline file,
but is sorted based on file names in outs, deps or params.
Also, the params inside each files are also sorted based on name.
However, the objects inside params are not sorted deterministically
as I think it's too much to sort that, and is not easy (considering
the types of objects it might hold, eg: lists, objects, etc).
This will also provide ordered dumps for Python3.5
* fix windows 3.8 test
