Subject: Azure: fix reformatting of ephemeral disks on resize to large types.

Large instance types have a different disk format on the newly
partitioned ephemeral drive. So we have to adjust the logic in the
Azure datasource to recognize that a disk with 2 partitions and
an empty ntfs filesystem on the second one is acceptable.

This also adjusts the datasources's builtin fs_setup config to remove
the 'replace_fs' entry. This entry was previously ignored, and confusing.
I've clarified the doc on that also.

LP: #1686514
