    Rewrite get_secgroup_uuids to avoid resource_by_refid

    get_secgroup_uuids has changed in the following ways:
    * No longer attempts to find a security group name via
      a resource_by_refid lookup. resource_by_refid only exists
      as a workaround for AWS compatibility resource which are
      not backed by an API. Usage of resource_by_refid should be
      avoided in native resources if at all possible.
    * If the security group looks like a UUID, assume it is
      a UUID for a security group that exists
    * Call client.list_security_groups only once, and only if
      there is a non-uuid security group specified
    * Do not attempt to reduce duplicate security groups to a unique
      list. If that is important for resources it can be done in
      validation.
    * Raise PhysicalResourceNotFound if name maps to no group
    * Raise PhysicalResourceNameAmbiguity if name maps to more than one
      group
