Sync remaining sample dashboards to latest version

The prometheus sample dashboard was updated in #245, so the rest should be updated as well.

• prometheus
• graphite
• influxdb
• postgres / timescale

Hi @nickbabcock - checking out the latest prometheus ds dashboard which looks great!

i'm seeing some smaller issues:

• Space in Network section

• Only one of two disks showing details
• Samsung Drive appearing twice because of two temp sensors
• Disk Temps having a max value of 100, the rest is auto

• graphics fan speed rpm having a threshold of 80

Greatly appreciate you taking a look and finding areas of improvement. I'll see what I can fix. Some of the issues may be limitations of Grafana where a workaround may be necessary.

• I can reproduce issue with space in network panel. It appears that Grafana isn't well suited where the leading panels are statically constructed and subsequent panels initialized with a repeated variable. The solution may be to move the network overview table panel outside the row -- or maybe I'm missing something 🤔
• I should be able to fix the drive issues
• Interesting to see the gpu fan speed issue. My assumption is that since the fan speed is 0, there is a division by zero as the threshold is calculated based on RPMs and percent load and when load has always been zero, so it is understandable that the threshold bugs out. Additionally the panel uses the "Config from query results" beta transformation, so even though the panel is cool when it works, there seems to be several edge cases 😅

Hi @nickbabcock - used the latest dashboard from master to see if things are fixed - drives only showing once now - sadly there still was no repeat for multiple harddrives

i searched a little bit and found info that for repeat to work you need to enable the include all option and use this as the variable dashboard default value. it is working fine for me

https://community.grafana.com/t/repeat-panel-not-repeating/17818

here is how it is configured now for me:

i also noted that some of the variables had been set to on dashboard load while others had been on time range change.

for the nic i simply resized my existing panel - thanks for you great work on these dashboards!

@swiffer perfect timing, I was just doing some additional hardware testing today! I filed a couple PRs that update the sample dashboard and fix the issues you pointed out.
