Adding maxPerRow for all panels and repeatDirection for row panel

[vishnuchalla]

These two attributes are required for below reasons.

• maxPerRow: To limit on the max repeating panels in a row.
• repeatDirection: To allow repeat direction either "h" or "v" for a row panel.

The files in gen/ are generated, please do not edit them by hand. Have a look at https://github.com/grafana/grafonnet/blob/main/DEVELOPMENT.md to see how the generate process works.

It looks like the schema for the row panel is missing these fields. These functions can be added in this file: https://github.com/grafana/grafonnet/blob/main/custom/row.libsonnet

Better would be an issue or PR against grafana/grafana to update the underlying schema. Then Grafonnet would automatically pick it up.

Grafana upstream already seems to be having these elements in their schema, as we can see them in the UI dashboard.

Made these changes in schema as suggested instead of generated files. I am not sure why make generate is not working in my local and running into below error.

@vishnuchalla You are missing jrsonnet

Hey, sorry for letting this hang for so long.

I've just been looking into this, trying to figure out why those fields aren't there. AFAICT these values don't make sense on a row panel, the direction is always vertical, regardless of the value in the json, that's just how rows work. The maxPerRow doesn't mean anything as nested rows don't exist.

repeatDirection is available on panels: example

maxPerRow fixed in #207 along with a few other fields.
