epmdless

[mhanberg]

Description

I would rather not have to deal with epmd and whether it is started automatically or not, or have people have to click another dialog on macOS that say "allow incoming connections".

The alternative is to use the epmdless (Hex) library to be able to cluster nodes locally without epmd.

Notes

• I believe we can avoid the dialog when the "beam" process boots up if I notarize and sign the macOS exes, but epmd is usually installed via the system package manager and will not be signed. This is another reason to find an alternative to epmd.
• Another alternative would be using a TCP server to communicate between the runtime nodes and the LSP node, but I'd rather not add another layer of complexity (explicit complexity, one can argue clustering is implicit complexity).
