// AlterConfigsRequest issues a request to alter either topic or broker
// configs.
//
// Note that to alter configs, you must specify the whole config on every
// request. All existing non-static values will be removed. This means that
// to add one key/value to a config, you must describe the config and then
// issue an alter request with the current config with the new key value.
// This also means that dynamic sensitive values, which are not returned
// in describe configs, will be lost.
//
// To fix this problem, the AlterConfigs request / response was deprecated
// in Kafka 2.3.0 in favor of the new IncrementalAlterConfigs request / response.
// See KIP-339 for more details.
