This is a fixup release, as 1.6.7 was missing important changelog.

See merge request !285

whitelistfirewall manager is locking down partition access as configured in
partition's .slapos-whitelist-firewall file by using firewalld configuration.

The md5sum of last generated partition whitelist file is used to take
decision if given rule shall be updated.

The manager supports partition setup and destruction.

Note: User id is used with netfilter owner module, as currently the sourcing
      address is not enforced to be per partition.

Despite promise failure, managers shall be executed, as often thanks to
running them, promise can be fulfilled.

    Whenever a rss feed is disabled, we can use this form to render a legacy message that changes url and pubDate once a day.

   A general warning can be issued to warn all users regardless the context. This is usefull for general mantainence or custom messages, while it is urgent inform users right the way.

Some recipes (like softwaretype) need a reference for the partition
address and in webrunner, we don't have tap interface.
