Set windows docker client version to lowest supported

[glinton]

As pointed out in #4666, the lowest docker version windows supports is 1.24. NegotiateAPIVersion isn't an option because it only downgrades the client to the server version, since the client in telegraf is set lower than docker will ever report, it does nothing.

Ideally we'd quit supporting EOL docker versions that require older docker clients and go back to using 1.24 for all distributions. Would revert change made in #4434 to support deprecated versions of docker 😳.

I don't think this fix can work, since docker is often collecting over the network. For example, you may be collecting from Windows Docker over the network from Linux.

@glinton I think that if you add another check that if host value starts with npipe: then it is bullet proof as that is possible only if Telegraf is running on Windows and it is connecting to local Docker installation.
