Issue 3191 - Move filtermaster::repo_download to a distinct file

modules/filtermaster/manifests/repo_download.pp

+# == Type: filtermaster::repo_download
+#
+# Manage filter list download source repositories for aggregation.
+#
+# === Parameters:
+#
+# [*alias*]
+#   An optional alias for use as the download resource name, allows for
+#   repositories with different names. Note that this option is recognized
+#   only when setup via hiera('filtermaster::repo_downloads')!
+#
+# === Examples:
+#
+#   filtermaster::repo_download {'exceptionrules':
+#     alias => 'exceptions',
+#   }
+#
+define filtermaster::repo_download (
+  $alias = $title,
+) {
+
+  $directory = "/home/rsync/subscription/$title"
+  $repository = "https://hg.adblockplus.org/$title"

IMHO $name would be a better fit here, but the docs clearly recommend using
$title when one's not sure..

+
+  ensure_packages(['mercurial'])
+
+  exec {"fetch_${title}":

Maybe we should rename this part to be more verbose and less likely to collide,
as done in other newly developed code already. E.g.:
"filtermaster::repo_download#$title".

+    command => shellquote('hg', 'clone', $repository, $directory),
+    onlyif => shellquote('test', '!', '-d', $directory),
+    path => ['/usr/local/bin', '/usr/bin', '/bin'],
+    require => Package['mercurial'],
+    timeout => 0,
+    user => rsync,
+  }
+}
