Stores the account and certificates data in two files:
{path}/accounts.json
{path}/certificates.json
Uses MongoPortable
to write to and query the files, though manual edits,
should be easy enough if required.
Supports only one option path
which will be the directory that the files are
stored in. Please not that this path cannot be /
(root).
Unlike le-store-certbot
certificate files are not created as such the
certificates must be extracted to be used.
