The flag `--es.slm` has been renamed to `--collector.slm`.

* [CHANGE] Rename --es.slm to --collector.slm #XXX
The logging system has been replaced with log/slog from the stdlib. This change is being made across the prometheus ecosystem. The logging output has changed, but the messages and levels remain the same. The `ts` label for the timestamp has bewen replaced with `time`, the accuracy is less, and the timezone is not forced to UTC. The `caller` field has been replaced by the `source` field, which now includes the full path to the source file. The `level` field now exposes the log level in capital letters.

* [CHANGE] Rename --es.slm to --collector.slm #932
* [CHANGE] Replace logging system #942

Logging by the exporter is handled by the `log/slog` package. The output format can be customized with the `--log.format` flag which defaults to logfmt. The log level can be set with the `--log.level` flag which defaults to info. The output can be set to either stdout (default) or stderr with the `--log.output` flag.

#### Elasticsearch 7.x security privileges

Username and password can be passed either directly in the URI or through the `ES_USERNAME` and `ES_PASSWORD` environment variables.
