switch to pyproject.toml

[zzstoatzz]

i started on this branch trying to improve import strategies but after profiling with cProfile i saw that a lot of time was being spent doing versioneer stuff and read that using setuptools_scm can improve this.

based on

» pytest --benchmark-only --benchmark-min-rounds=10 benches/bench_import.py

Test	Main (ms)	Branch (ms)
bench_import_prefect	66.04	0.66
bench_import_prefect_flow	314.68	242.98

I think there are many good reasons to switch to setuptools_scm over versioneer

• we already use it in collections
• versioneer is unmaintained
• edit all config in one place (instead of setup.py, setup.cfg and requirements*)
