Puppetboard

-----

* Show user-friendly error message when there's a problem with connecting to the PuppetDB and just zeros instead of HTTP 404 when the PuppetDB is just yet empty ([PR 692](https://github.com/voxpupuli/puppetboard/pull/692),
* Add a healthcheck to the Docker image ([PR 690](https://github.com/voxpupuli/puppetboard/pull/690)),
* Fix Failures view when there are no logs ([PR 693](https://github.com/voxpupuli/puppetboard/pull/693)).

-----

* Fixed friendly error message toggle (when there is no env in the URL) ([688](https://github.com/voxpupuli/puppetboard/issues/688)).

-----

* **Report** view improvements:
* show Logs before Events as they are more useful,
* show different, arguably more useful columns in Logs by default,
* allow showing messages in a "friendly" mode (like in Failures view),
* make Logs and Events filterable,
* don't force column sizes for a better, automatic content layout,
* use fixed-width font where it makes more sense,
* Fix mixed up normal and OFFLINE_MODE for Query view.

-----

* Fix auto-resize in radiator view,
* Fix Query tab cannot be disabled on Docker
* Removed unused import in setup.py,

-----

* **Query** view improvements:
* Make the result clickable if a certname is in it ([652](https://github.com/voxpupuli/puppetboard/pull/652)).
* UX improvements: show the number of results, show a user-friendly error in case of a PQL syntax error, show a warning on empty result, use fixed-width font for matching the query with the possible error message, remove useless 'Cancel' button. ([653](https://github.com/voxpupuli/puppetboard/pull/653)).
* Add 'Download as CSV' and 'Download as XLSX' to the results ([654](https://github.com/voxpupuli/puppetboard/pull/654)).
* Make the result shareable using URL ([657](https://github.com/voxpupuli/puppetboard/pull/657)).
* New **Failures** view for showing the first error/failed resource for all nodes with a failed puppet run. It can show both "friendly" and raw error messages ([662](https://github.com/voxpupuli/puppetboard/pull/662)).
* Sort 'uptime' fact values correctly ([591](https://github.com/voxpupuli/puppetboard/pull/591)).
* Visual tweaks ([667](https://github.com/voxpupuli/puppetboard/pull/667)).
* Improvements for running with Docker:
* Configurable binding host in Dockerfile ([660](https://github.com/voxpupuli/puppetboard/pull/660)).
* Allow passing PuppetDB certificates via environment variables when using Docker, in base64 encoding or not ([671](https://github.com/voxpupuli/puppetboard/pull/671)).
* Add Puppet code for running Puppetboard using Docker into the README ([672](https://github.com/voxpupuli/puppetboard/pull/672)).
* Add missing fonts and icons to the PyPI package ([666](https://github.com/voxpupuli/puppetboard/pull/666)).
* Refactoring: split views into separate files ([665](https://github.com/voxpupuli/puppetboard/pull/665)).
* Update many dependencies.
