Include Elementary::Connection in the root .rb file
Only create one instance of an executor per connection

This will make sure that we properly use keepalives, etc
Only construct a relative path for Faraday when accessing a specific RPC endpoint

Faraday is too clever and if you lead with a slash it will obliterate the prefix if it exists.

E.g. for  "http://localhost/rpc"

With a leading slash this becomes "http://localhost/mymethod"
Without it becomes "http://localhost/rpc/mymethod"
