Stabilization towards 1.0 release:
* Support newer `python-acme` releases
* handling nonce errors (with updated acme library), fixes 8
* switch to ACME v2 endpoints
* support for wildcard domains
* a basic logging framework, fixes 3
* test against multiple ACME backends (https://github.com/letsencrypt/boulder
and https://github.com/letsencrypt/pebble)
* use docker-compose for simple and reliable ACME backend setup
* Refresh supported Python versions (add new released major versions,
drop unsupported old ones): target 3.5 to 3.8 for now
* Dedicated HTTP error codes for rating limiting and validation errors
* Simplified Python dependencies: only use PyOpenSSL and cryptograph to
parse CSR and during tests
