Examples: Add log data source

[ivanahuckova]

Based on conversation with @xnyo I am creating a PR that adds a new datasource example with datasource that implements logging features. The datasource just mocks receiving of logs trough mockDataRequest.ts. Let me know if there is anything I need to change/update. 🙂

Just wanted to check on this - if you've had time to review/have any feedback 🙂

Awesome work!! Sorry if this took so long 😞

I took it up for a spin and it works really well 👏 👏

Looks great so far! I only have a few comments:

It would also be great to see how it would look like combined with a backend component, rather than frontend-only, but that's something that we look into later on.

@xnyo the integration test is failing on Build plugin with canary_version @grafana dependencies but not sure how to debug that. Do you have any thoughts?

Okay, I was able to figure it out. Seems like @swc/core version was an issue and this https://stackoverflow.com/questions/76884057/grafana-build-a-panel-plugin-from-template-error helped me to resolve it. Interestingly, all other examples in this repo use the same 1.3.75 version, so it seems like it is a known issue. Have you considered changing dependency to version in template to 1.3.75 as it works, compared to other versions.

LGTM!

It looks like this has been bumped to ^1.3.90 in the latest template: https://github.com/grafana/plugin-tools/blob/18adb4b38dc283c7a7d10c8355580cbdad96e72e/packages/create-plugin/templates/common/_package.json#L26
