webdav-centos7/Dockerfile is broken

[vrbanecd]

1. One of the links in the docker file is wrong (line 15): instead of https://repo.cloud.cnaf.infn.it/repository/storm/nightly/storm-nightly-centos7.repo it seems it should be https://repo.cloud.cnaf.infn.it/repository/storm/storm-nightly-centos7.repo.

2. When I run the container (docker run -it storm-webdav bash) and in the container I do service storm-webdav start I get an error:
   Redirecting to /bin/systemctl start storm-webdav.service Failed to get D-Bus connection: Operation not permitted

When I tried to troubleshoot I found that the file in line 5 of run.sh doesn't exist. The error message is /etc/sysconfig/storm-webdav: No such file or directory.
