  1. rabbit_env: Add $RABBITMQ_DEFAULT_{USER,PASS,VHOST} and $RABBITMQ_ERL… 

    …ANG_COOKIE vars

Those environment variables are unset by default. The default values are
set in the `rabbit` application environment and can be configured in the
configuration file. However, the environment variables will take
precedence over them respectively if they are set.

  2. Add support for $RABBITMQ_DEFAULT_{USER,PASS,VHOST} env vars 

    They are the equivalent of the `default_{user,pass,vhost}` configuration
settings. Each set environment variable will take precedence over its
configuration file counterpart.

Fixes docker-library/rabbitmq#508.

  3. Add support for $RABBITMQ_ERLANG_COOKIE env var 

    It is the equivalent of the content of the Erlang cookie file. Note this
variable IS the cookie value, NOT the path to a cookie file.

If it is set, it will take precedence over the content of the Erlang
cookie file.

Fixes docker-library/rabbitmq#508.

  4. Log a warning when Erlang cookie is overriden using an env variable 

    as it can be really difficult to troubleshoot such cookie changes
