module: hwc_vpc_security_group
description:
    - vpc security group management.
short_description: Creates a resource of Vpc/SecurityGroup in Huawei Cloud
notes:
    - If O(id) option is provided, it takes precedence over O(name),
      O(enterprise_project_id), and O(vpc_id) for security group selection.
    - O(name), O(enterprise_project_id) and O(vpc_id) are used for security
      group selection. If more than one security group with this options exists,
      execution is aborted.
    - No parameter support updating. If one of option is changed, the module
      will create a new resource.
