Pranav Kant bcf958c500 wsd: Fail gracefully when storage misbehaves
When WOPI's CheckFileInfo or GetFile responds with status code other
than HTTP 200, show a message to the user indicating some problem in the
storage.

Currently, we open an empty document if storage doesn't return a
document which surely is not correct.

Mention the storage server address when asking user to contact the
server administrator to be more friendly.
