Create forkmon for EL monitoring

[barnabasbusa]

Use forkmon for monitoring EL block height:

I have tried to reference the el_service_name within a package of eth2-package? Looks like the def new_el_client_context(client_name, enr, enode, ip_addr, rpc_port_num, ws_port_num, engine_rpc_port_num, jwt_secret): are the only params available, and can't seem any easy way to reference a specific node pair's name. Ideally I want to have https://github.com/barnabasbusa/eth2-package/blob/main/src/el_forkmon/el_forkmon_launcher.star#L66
"Name": geth-lighthouse-0

When I add el_service_name as attribute to new_el_client_context https://github.com/kurtosis-tech/eth-network-package/blob/main/src/el/el_client_context.star#L1 each EL node will have no access to its node pair at the place of creation.
The only function that has access to both pairs seem to be https://github.com/kurtosis-tech/eth-network-package/blob/main/src/participant_network.star.

Not quite sure how to get the CL's to work with forkmon.
