Stop using deprecated zkcli.sh to setup security

[janhoy]

Operator uses zkcli.sh to upload security.json to zookeeper (https://github.com/apache/solr-operator/blob/main/controllers/util/solr_security_util.go#L241). Since this script is gone in 10.0 we should change this.

Here is an alternative way using bin/solr.

solr zk cp zk:/security.json /tmp/current_security.json >/dev/null 2>&1
if [ $? -eq 0 ]; then
    if [ ! -s /tmp/current_security.json ] || grep -q '^{}$' /tmp/current_security.json; then
        echo $SECURITY_JSON > /tmp/security.json
        solr zk cp /tmp/security.json zk:/security.json >/dev/null 2>&1
        echo "put security.json in ZK"
    fi
