LinuxDriver mixes in napalm-device-types' ServiceClustersMixin (4.17.0):
get_service_clusters() reads Patroni's members and roles, adguardhome-sync's
origin and replicas and a BunkerWeb worker's manager from the host's own
configuration -- the evidence that two hosts run one service, not merely
answer at one address (NetOrk/netork#1125). _run_service_clusters_command
carries the shared command on an exec channel, root first, like the virtual
IPs' one.
