rabbitmq-env.conf default settings for RabbitMQ AMQP server

## Description

`/etc/rabbitmq/rabbitmq-env.conf` contains variable settings that override the defaults built in to the RabbitMQ startup scripts.

The file is interpreted by the system shell, and so should consist of a sequence of shell environment variable definitions. Normal shell syntax is permitted (since the file is sourced using the shell "." operator), including line comments starting with "#".

In order of preference, the startup scripts get their values from the environment, from `/etc/rabbitmq/rabbitmq-env.conf` and finally from the built-in default values. For example, for the `RABBITMQ_NODENAME` setting,

`RABBITMQ_NODENAME`

from the environment is checked first. If it is absent or equal to the empty string, then

`NODENAME`

from `/etc/rabbitmq/rabbitmq-env.conf` is checked. If it is also absent or set equal to the empty string then the default value from the startup script is used.

The variable names in /etc/rabbitmq/rabbitmq-env.conf are always equal to the environment variable names, with the `RABBITMQ_` prefix removed: `RABBITMQ_NODE_PORT` from the environment becomes `NODE_PORT` in the `/etc/rabbitmq/rabbitmq-env.conf` file, etc.

For example:

    # I am a complete /etc/rabbitmq/rabbitmq-env.conf file.
    # Comment lines start with a hash character.
    # This is a /bin/sh script file - use ordinary envt var syntax
    NODENAME=hare

This is an example of a complete `/etc/rabbitmq/rabbitmq-env.conf` file that overrides the default Erlang node name from "rabbit" to "hare".
