The :eetcd Erlang library expects charlists, not binary strings.
This was causing a FunctionClauseError in :lists.reverse/1 because
it was receiving a binary string instead of a charlist.
Error:
(FunctionClauseError) no function clause matching in :lists.reverse/1
(stdlib 7.2) lists.erl:291: :lists.reverse("etcd-0.etcd...")
Solution:
Use ~c sigil to convert endpoint strings to charlists for the
Erlang library to consume correctly.
