eturnal 1.10.0

Added

• Include mod_stats_prometheus, a module for exporting metrics to Prometheus.
• Include an example configuration for logrotate.
• Include an example OpenRC init (and configuration) file.

Changed

• If an EPMD process was spawned during eturnal startup, stop it on shutdown,
  unless it's used by other Erlang nodes.

Fixed

• Avoid permission issues in the case where eturnalctl was invoked by root
  from a directory the user running eturnal isn't permitted to change into.
• Make sure eturnalctl daemon won't hang on the very first startup when using
  Erlang/OTP 23 or newer.
