Puppet class sitescripts does not create the /etc/sitescripts.ini file if no explicit settings/snippets are set up. Although this could be valid behavior in general, but in order to avoid the above issue we obviously need to ensure the file's presence even in those cases.

While the 1st patch-set ensures sitescripts.ini being present, we still need a follow-up:

Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

    projects = read_projects(config)
  File "/opt/sitescripts/sitescripts/docs/bin/generate_docs.py", line 26, in read_projects
    for key, value in config.items("docs"):
  File "/usr/lib/python2.7/ConfigParser.py", line 642, in items
    raise NoSectionError(section)
ConfigParser.NoSectionError: No section: 'docs'

In #3637 resource Cron['generate_docs'] was introduced, depending on sitescripts configuration section [docs] which, so far, is not always included. This leads to the above error on static web::server nodes.
