Add support for `post-status` property
As part of being able to publish draft content, such as Week Notes,
ahead of post being moved to be "ready", we need to support hte
Microformats", we need to support the Microformats property
post-status
.
We'll support published
and draft
for now, and reject any requests
that are outside of these values.
In the case that this is set to draft
, we set the Hugo draft
property to ensure Hugo presents it as a draft post, and does not
publish it.
