Add support for collecting arbitrary metrics from a textfile as well as metrics collected from fail2ban. This allows other data to be exported along with the fail2ban metrics (e.g. instance metadata). Update the docker image to allow mounting a folder with a collection of metric files to be exported. Only files ending in `.prom` with be read. Update project README with the new functionality.
