Format and sanitize Grafana dashboards
Usage: {} <DIRECTORY|FILE>
The program will:
* Sort keys alphabetically.
* Remove sections:
templating.list[].current
templating.list[].options
* Override the time entry to {{"from": "now-1h","to": "now"}}
* Enable the sharedCrosshair tooltip
* Increment the version number
WARNING: this script modifies directly the given file(s).
If a DIRECTORY is provided, all files with suffix '.json' are modified.
