* remove healthcheck sidecar, perform probes in etcd
container itself, failing liveness probes in sidecar
do not restart problematic etcd container;
* verify that etcdctl member list cmd in anchor is
always successfull;
* adjust ETCDCTL_ENDPOINTS env in etcd container to
POD_IP variable instead of localhost (127.0.0.1);
* add liveness/readiness probes to auxiliary etcd as
well as properly passing etcd configuration variables
as strings;
* monitor current leader in initial etcd cluster, in case
if aux member is current leader pass it to permenant
member, same check applies for aux suicide process;
* etcd aux pod will be alive unless all permanent nodes
come up and join the cluster plus apiserver no longer
relies on aux members;
* add 5 seconds sleep between aux member remove for more
smooth transition process.
