CosmosFullNode: Add support for additional ports

[karlmjogila]

There isn't an option to add additional ports to the podTemplate at the moment.

I would like to expose EVM RPC ports (8545 and 8546 ) as well and at the moment, that is not possible unless I reconfigure the ports in app.toml.

Is this really not possible? How does it work with a remote signer then?
