Option to log process arguments

[gagan-bansal]

Explore option to log process arguments. This may be useful in case of service.js as a service and act based on the process arguments.

Like a queue consumer service program process many queues and queue name is passed as process arguments. It would be nice if queue name is logged in all modules' log.

Example:

$ MUNIA_PROCESS_ARGV=1 node service.js  --queue foo &
$ MUNIA_PROCESS_ARGV=1 node service.js  --queue bar &

Log:

{"module": "service.js", "level":"info", "consuming RabbitMQ" , "queue":"foo", ...}
{"module": "service.js", "level":"info", "consuming RabbitMQ" , "queue":"bar", ...}
{"module": "my-rabbitmq.js", "level":"info", "acknowledged the content" , "queue":"foo", ...}
{"module": "my-rabbitmq.js", "level":"info", "acknowledged the content" , "queue":"bar", ...}
