[tornado/snmptrapd_collector] Add docs for configuration ENV variables

The snmptrapd_collector was loaded successfully.

+### Configuration options
+The address of the Tornado Engine TCP instance to which the events are forwarded
+is configured with the following environment variables:
+- __TORNADO_ADDR__: the IP address of Tornado Engine. If not specified,
+it will use the default value _127.0.0.1_
+- __TORNADO_PORT__: the port of the TCP socket of Tornado Engine. If not specified,
+it will use the default value _4747_
+
## How It Works
The snmptrapd_collector receives snmptrapd messages, parses them, generates Tornado Events
and, finally, sends them to the Tornado TCP events socket.
-The current version, will always use these hardcoded values to find the Tornado engine:
-- Tornado engine IP address: _127.0.0.1_
-- Tornado engine port: _4747_
-
The perl script should automatically reconnect in case the Tornado engine is
temporarily not available.
