T5222: Refactoring load-balancing reverse-proxy

Improve and refactoring "load-balancing reverse-proxy"

 - replace 'reverse-proxy server <tag>'
        => 'reverse-proxy service <tag>'

 - replace 'reverse-proxy global-parameters tls <xxx>'
        => 'reverse-proxy global-parameters tls-version-min xxx'
        => 'reverse-proxy global-parameters ssl-bind-ciphers xxx'

 - replace 'reverse-proxy service https rule <tag> set server 'xxx'
        => 'reverse-proxy service https rule <tag> set backend 'xxx'

  'service https rule <tag> domain-name xxx' set as multinode
