eturnal 1.8.0

Added

• Allow for configuring TLS connection properties using the new tls_options,
  tls_ciphers, and tls_dh_file options (#6).
• Allow for specifying a whitelist of IP addresses/subnets which will be
  accepted even if they would otherwise be rejected due to being matched by a
  blacklist (#12).
• Don't close active TURN sessions when ephemeral credentials expire, by
  default. The new strict_expiry option allows for enabling the previous
  behavior.
• Add eturnalctl disconnect $user command for closing any TURN session(s) of
  the specified $user name.
• Let the eturnalctl sessions command accept an optional $user argument to list
  only the TURN session(s) of the specified $user name.
• Support running eturnal without the Erlang Port Mapper Daemon (EPMD)
  by specifying the environment variable ERL_DIST_PORT (requires at least
  Erlang/OTP 23.1 and Rebar3 3.18.0).

Changed

• Binary release: Run eturnal without EPMD (as described above).

Fixed

• Don't log bogus error messages if no eturnal modules are enabled when using
  Erlang/OTP version 21.0, 21.1, or 21.2.
• Binary release: Don't let Erlang/OTP link against libnsl.so.1, which is no
  longer shipped by default on RedHat-based distributions, and isn't actually
  needed (#19).
