Scaleway: add datasource with user and vendor data for Scaleway.

Here we add and enable by default a datasource for Scaleway cloud.
The datasource quickly exits unless one of three things:
 a.) 'Scaleway' found as the system vendor
 b.) 'scaleway' found on the kernel command line.
 c.) the directory /var/run/scaleway exists (this is currently created
     by the scaleway initramfs module).

One interesting bit of this particular datasource is that it requires
the source port of the http request to be < 1024.
