Grid layout bug fix

v2.3.1

Build version bump.

Grid layout

Thanks to @dwitzig for adding grid layout. This allows your report panels to be arranged in a grid that resembles the original Grafana dashboard layout. See #162 for some example images.
This layout also addresses some bugs related to the previous fixed size panels rendering (#119, #80, #72).

Improved first try experience by returning a helpful message from the '/' URL.

Include windows and linux binaries in release.

Small bug fixes to 2.2.0 release

• Issue #143 fixed by PR #145. Thanks to @bolsunovskyi.
• PR #146 addresses the bug that the new sslCheck flag wasn't getting passed through all the way to the Grafana render PNG panel calls. Thanks to @cr1xu5 .

Command-line mode and other improvements

Thanks to the following contributors:

• @bolsunovskyi for adding support for commandline mode to the reporter. This allows you to use the reporter directly from the command line instead of as a webserver over a REST API. See the readme for details.
• @krysalead for making it possible to disable SSL verification of the grafana certificate. This is still enabled by default. See the readme for details.
• @sbaier1 for reducing the docker image size from 1Gb to about 100Mb.

I also clarified the readme with some more examples for authentication and custom LaTeX templates.

Various improvements

Improvements:

• Text panels no longer fixed height (#52)
• Report timezone determined by server. Thanks to @thnurg for investigating (#43)
• Set filename and extension to use when downloading file. (#62)

Thanks to the following contributors for their fixes:

• @Flowm for fixing timestamp parsing on 32bit systems (#54)
• @jkreileder for fixing relative time specifications to include also work for positive relative time (#71)
• @vryzhaiev for fixing the docker build and adding ca-certificates to the docker image (#74)

Bug fixes

Addressed the following issues: #40, #38.
Improved error handling and feedback.
Added image to Dockerhub: #37.

Grafana v5.0 support

Support the new Grafana dashboard HTTP API and dashboard JSON structructure introduced in Grafana 5.0. This has been done by introducing a new grafana-reporter endpoint that deprecates the previous one. The previous endpoint is still available but may be dropped in a future release. See readme.md for usage details.

Dropped bundled enhanced.tex template; it uses dashboard Rows extensively and Rows have been dropped from the Grafana 5 data model.

Support for Grafana variables

Added support for Grafana variables. Mulitple variables should be supported. See the Query parameters section of the readme.

Exposed some more of the dashboard metadata to the report template

Makefile added with options for building docker a image. See readme.

Thanks to @nktl, @chiefy and @JCN-9000 for their contributions.

Initial open source release

Version management of this project has been lacking, so this version number fuzzily includes all changes prior to 1.0.0.
