Additional network protocol support

Add the following network protocol support to the
"os security group rule create" command:
  - Add "--icmp-type" and "--icmp-code" options
    for Network v2 only. These options can be used to set
    the ICMP type and code for ICMP IP protocols.
  - Change the "--proto" option to "--protocol". Using the
    "--proto" option is still supported, but is no longer
    documented and may be deprecated in a future release.
  - Add the following Network v2 IP protocols to the
    "--protocol" option: "ah", "dccp", "egp", "esp", "gre",
    "igmp", "ipv6-encap", "ipv6-frag", "ipv6-icmp",
    "ipv6-nonxt", "ipv6-opts", "ipv6-route", "ospf", "pgm",
    "rsvp", "sctp", "udplite", "vrrp" and integer
    representations [0-255].

The "os security group rule list" command now supports
displaying the ICMP type and code for security group rules
with the ICMP IP protocols.
