Is your feature request related to a problem? Please describe.

It would be helpful to provide the example bitcoin.conf provided in the source code to the users that just download the binary/install from their package manager.

Secondly, a new bitcoind user may not be aware that bitcoin.conf file is an available option. While bitcoin.conf is mentioned in the man page, one would have to know what to look for or read a bit to get to the -conf section. By providing a skeleton file, a new user is more exposed to such an option.

Describe the solution you'd like

Automatically generate a skeleton bitcoin.conf with something like the one found at share/examples/bitcoin.conf when first starting bitcoind.
