Running pg_web_stats directly from Docker Hub

[nyurik]

Thanks for making this! Could you publish it to the docker hub and add readme instruction on using? A single line command is far more preferable than cloning/configuring/running it by hand.

Something like
docker run -it --rm --net host kirs/pg_web_stats -h pghost -p pgport -U pgusername
similar to psql, plus a few extra params for serving itself, e.g. binding address / port.
