[analyse] grafana unmarshal errors

[AkashSirimanna]

Problem

Running analyse grafana on version 0.10.7 of cortextool does not complete 100% successfully. The tool has difficulties trying to unmarshal panel json, most likely due to the tool not being compatible with Grafana 8.3.4.

The errors are along the lines of

unmarshal board: json: cannot unmarshal object into Go struct field Board.panels of type []struct { Type string "json:\"type,omitempty\""; Params []string "json:\"params,omitempty\"" }

OR

unmarshal board: json: cannot unmarshal number 4.8 into Go struct field Board.panels of type int ...
unmarshal board: json: cannot unmarshal object into Go struct field Board.panels of type string ...

Due to this, the metricsUsed list the analyse commands returns is incomplete.

Tagging @hjet per our discussion today - I'm seeing this issue also against Grafana 8.4.x

Related: grafana-tools/sdk#190
And: grafana-tools/sdk#201

Temporary workaround (uses grafana-tools/sdk#190 branch of sdk):

git clone git@github.com:grafana/cortex-tools.git
git checkout temp-update-grafana-sdk
make cortextool

The binary will be at cmd/cortextool/cortextool. Move that to inside your path.

This error appears to still be happening

Indeed, still failing (using with Grafana v10.0.1 - 5a30620b85)
