  // configurations owned by your AWS customer account.
  //
  // If you specify both tag keys and tag values in the same request, Amazon Redshift
  // returns all HSM connections that match any combination of the specified keys
  // and values. For example, if you have owner and environment for tag keys,
  // and admin and test for tag values, all HSM connections that have any combination
  // of those values are returned.
  //
  // If both tag keys and values are omitted from the request, HSM connections
  // are returned regardless of whether they have tag keys or values associated
  // with them.
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
