Plugin 'sql' does not support multi workers configuration (Fluent::Plugin::SQLOutput)

[micdobro]

Any reason for not supporting multi worker configuration on output?

Using td-agent 4.3.0 fluentd 1.14.3 (438a82aead488a86180cd484bbc4e7e344a9032b). It looks like all SQL output plugins don't support it at all.
