In progress
* get directory
* get nonce
* create account
* new order
* get challenges
* Mar 15, 2018 - get directory
* Mar 15, 2018 - get nonce
* Mar 15, 2018 - generate account keypair
* Mar 15, 2018 - create account
* Mar 16, 2018 - new order
* Mar 16, 2018 - get challenges
* Mar 20, 2018 - respond to challenges
* Mar 20, 2018 - generate domain keypair
* Mar 20, 2018 - finalize order (submit csr)
* Mar 20, 2018 - poll for status
* Mar 20, 2018 - download certificate
Not yet tried
* Mar 20, 2018 - SUCCESS - got a test certificate (hard-coded)
* respond to challenges
* finalize order
* poll for status
* download certificates
Todo
* match api for acme v1 (le-acme-core.js)
* make not hard-coded
