[pmg-devel] [PATCH acme-rs 2/8] add meta fields returned by the directory

[Folke Gleumes <f.gleumes@proxmox.com>]

According to the rfc, the meta field contains additional fields that
weren't covered by the Meta struct. Of the additional fields, only
external_account_required will be used in the near future, but others
were added for completeness and the case that they might be used in the
future.
