clients: build filtered clients group early

when the group `_filtered_clients` is built, the order can change from
the original `clients` group which can cause issues since we run
`ceph-container-engine` on the first client only. It means later in the
playbook we can make call to the container CLI on a node where the
container engine wasn't installed.
