##### SUMMARY

Two vmware modules uses `copy()` to duplicate an internal instance of a pyvmomi object. This to be able to modify the object during an iteration.

As explain here, https://github.com/ansible/ansible/pull/60196/files#r312643761 this is not the best approach and this may impact the performance.

    - Specify the state the virtual machine should be in.
    - 'If C(state) is set to C(present) and virtual machine exists, ensure the virtual machine
       configurations conforms to task arguments.'
    - 'If C(state) is set to C(absent) and virtual machine exists, then the specified virtual machine
      is removed with its associated components.'
    - 'If C(state) is set to one of the following C(poweredon), C(poweredoff), C(present), C(restarted), C(suspended)
      and virtual machine does not exists, then virtual machine is deployed with given parameters.'
    - 'If C(state) is set to C(poweredon) and virtual machine exists with powerstate other than powered on,
      then the specified virtual machine is powered on.'
    - 'If C(state) is set to C(poweredoff) and virtual machine exists with powerstate other than powered off,
      then the specified virtual machine is powered off.'
    - 'If C(state) is set to C(restarted) and virtual machine exists, then the virtual machine is restarted.'
    - 'If C(state) is set to C(suspended) and virtual machine exists, then the virtual machine is set to suspended mode.'
    - 'If C(state) is set to C(shutdownguest) and virtual machine exists, then the virtual machine is shutdown.'
    - 'If C(state) is set to C(rebootguest) and virtual machine exists, then the virtual machine is rebooted.'

    - Name of the virtual machine to work with.
    - Virtual machine names in vCenter are not necessarily unique, which may be problematic, see C(name_match).
    - 'If multiple virtual machines with same name exists, then C(folder) is required parameter to
       identify uniqueness of the virtual machine.'
    - This parameter is required, if C(state) is set to C(poweredon), C(poweredoff), C(present), C(restarted), C(suspended)
      and virtual machine does not exists.
    - This parameter is case sensitive.
    required: yes
