When building against go-ceph, the most recent version of Ceph is
assumed to be available (currently Octopus). In case an older version of
the development packages is installed, building go-ceph will fail.
Golangci-lint does not accept the `-tags nautilus` parameter like other
Golang tools. Instead, the build-constraints need to be configured in a
confguration file.
This change takes care of the following:
- move the current scripts/golangci.yml to a template
- add the @@CEPH_VERSION@@ substitute
- generate the configuration file when needed
