Add compute response schema for microversion 2.98

Compute microversion 2.98 added the image properties field to the
following API responses:

* GET /servers/{server_id}
* GET /servers/detail
* POST /servers/{server_id}/action (rebuild)

While testing this it was discovered that microversion 2.96 is missing
an API response schema for:

* POST /servers/{server_id}/action (rebuild)

so this is also fixed in this patch.
