Don't require passing in port_security=False if security groups

[Aaron Rosen]

If creating a port on a network that is marked port_security_enabled=False and one passes in a security_group in the port_create request previously an error was raised saying they needed to also pass in port_security_enabled=False. Instead it would be better if we didn't require them to pass port_security_enabled=True explicitly and just default it to true if they pass in a security_group.

    Don't require passing in port_security=False if security_groups present

    If creating a port on a network that is marked as port_security_enabled=False
    and one passes in a security_group in the port_create request previously an
    error was raised saying they needed to also pass in
    port_security_enabled=False. This patch removes that requirement and instead
    sets port_security_enabled=True internally if a port has an ip_address and a
    security_group is passed in. This is more convient and does not break
    backwards compatibility.
