Added noMethodLog option

[satorumpen]

I added a option do not output RPC method name.

Hi @satorumpen. Thanks for this contribution. Can you please explain why this change is needed?

I think rather than having special logging flags in our already overgrown options object, it's likely better to switch to a proper logging library with logging keys and log levels. I've used winston for this in the past.

@benjamincburns Thanks for your reply.

I use it via ganache-cli, but I want to suppress the display of Polling method like eth_getFilterChanges. In this case, I think that the way to replace the logger with the logger option as you say is too excessive.

Please let me know your opinion.

@satorumpen as I said before, switching the default logger out for something more configurable (like winston) would be a more ideal approach to solving this problem. Otherwise in the interim you're welcome to set up your own logger object which filters out RPC calls you don't want to see in your logs.

If you're interested in making a contribution along those lines (adding a proper logging library) please open a new PR.
