* plugin/kubernetes: remove bunch a string ops This removes a bunch of appends to where not needed, makes dnsutil.Join take variadic args which removes the need to wrap in a new string slice. Signed-off-by: Miek Gieben <miek@miek.nl> * Fix calls to dnsutil.Join Signed-off-by: Miek Gieben <miek@miek.nl> * Revert these Signed-off-by: Miek Gieben <miek@miek.nl>
