Separate config.ini files for node and rpc

[nsjames]

Right now on first run of the eos-evm-node a config-files/config.ini is created which has value for both the eos-evm-node and the eos-evm-rpc.

Uncommented out keys and adding values works for the eos-evm-node, but then prevents the eos-evm-rpc from being able to be run without manually specifying another config.ini file with only the rpc values.

nsjames@ubuntu:~/eos-evm$ eos-evm-rpc --api-spec=eth,debug,net,trace --chain-id=17777 --http-port=0.0.0.0:8881 --eos-evm-node=127.0.0.1:8080 --chaindata=./chain-data
  CRIT [04-30|15:52:20.520 UTC] Unknown option 'chain-data' inside the config file /home/nsjames/eos-evm/config-dir/config.ini

eos-evm-node --help prints also options for rpc_plugin. I suppose, rpc_plugin should not be even compiled into the node.
