* provider/scaleway: fix bootscript tests
the bootscript tests where failing because the referenced bootscript is no
longer available.
for now this just makes the tests pass again, next step should be to lookup a
bootscript so we don't have to update the tests all the time
* provider/scaleway: fix bootscript data source filter bug
when providing a name only the architecture was ignoerd, which can lead to
issues since some bootscript names are identical, even though the architecture
is different.
* provider/scaleway: remove data bootscript exact name test
the test fails after some time because scaleway removes older bootscripts.
let's just settle with filtered tests for now, which don't have this problem.
bootscripts allow you to start Scaleway servers with a specific kernel version.
The `scaleway_server` has always had a bootscript parameter, and the
`scaleway_bootscript` datasource allows you to lookup bootscripts to be used in
conjunction with the `scaleway_server` resource.
