remco v0.6.0

Bug fixes

• 3be9d39 log the output of a failed command (check or reload)
• 040aaf0 fixed a pongo2 related data race
• 03cfe5f all backends of one resource need to connect cleanly now to prevent broken config files
• 7acb32c make sure to process a resource with ALL backends on startup. We don't render the config if one backend fails. Retry on error until success (every 2 Seconds) or the ctx is canceled

New features

• #2 added support for a include_dir directive in the config file so that template resources can be better structured (example resource config can be found in the docs)
• #3 With this little change watch and interval processing is not longer mutual exclusive.
  You can watch for changes and run the interval processor as a reconcilation loop.
