Issue with remote event subscription

Hi,

I'm trying to write a config that queries a remote server for Windows Events. My config looks like this:

```

@type windows_eventlog2
@id windows_remote
@log_level trace
read_existing_events false
read_interval 2
tag winevt.remote
rate_limit 200

@type local
persistent true
path C:\opt\td-agent\winevt-remote.pos

channels ["System"]
read_existing_events false
read_all_channels true
remote_server web-01.
remote_domain
remote_username Administrator
remote_password

@type stdout

```

And it seems as if no remote events are ever fetched. Instead, it seems to be getting local events for some reason, as per the following output from running this locally (the dc is the local machine running this in my testing environment):

```

Any advice as to how to proceed in troubleshooting this? I am not sure what those "parameter is not used" - maybe I have misconfigured something?

No source files or tests are named in the report. Start at the windows_eventlog2 source and its configuration handling, then trace the "parameter ... is not used" warnings and remote subscription path; done means the cause of local rather than remote event collection is identified and a reproducible configuration or fix is documented.
