BIRD-LG currently keeps log files indefinitely. This patch allows setting the number of days logs should be kept for by adding a `LOG_NUM_DAYS` parameter in the configuration files. This change is backwards compatible: Running the updated code with old configuration files will keep logs indefinitely as before; new deployments based on the example configuration will keep logs indefinitely.
