[ADD] subreports

[sbidoul]

Closes #155

With this PR, you can add named "sub reports" on a report template.
When that is done, KPIs from sub reports can be used in expressions of the the parent report with the following syntax <subreport name>.<kpi name>.

The code is WIP and will be refactored, but the concept and data model should be ok.

Hi, @sbidoul thanks!

I ran the tests on the runbot, it seems to be working well.

http://3408304-256-4348a7.runbot1.odoo-community.org/web#id=4&view_type=form&model=mis.report.instance&active_id=4

However, I don't know if I didn't know how to configure it, but the budget columns didn't work.

Another very interesting feature that we did in the PR of v8, was the possibility for the user, when viewing the report, to navigate to the subreport by clicking on the cell. https://github.com/OCA/mis-builder/pull/153/files#diff-3678f60340076198a6cc144a9fa4a107L37

Can we help you in any way?

Best regards

the budget columns didn't work.

Yes, that's expected. That should work after the refactoring.

Regarding the drilldown I'm not sure. Currently the drilldown shows move lines or budget lines. I tend to think showing other reports could be confusing because there could be many of them for different periods, or different preset analytic filters. Maybe something could be possible with the the features that generates reports instances on the fly. Need to think about it.

Can we help you in any way?

Thanks for proposing! Let me go through the refactoring first.

@mileo in the end, budget with subreports is not that obvious. Budget by account will work though.
For budget by KPIs to work with subreports, we probably need to extend mis.budget to either create a budget that allows budgeting KPIs from all subreports. Or make the budget source a m2m so the user can provide a budget for each subreport when defining a budget column. And that probably requires finding a good design that allows combining budget by account and budget by KPI in a single report. So that definitely requires more design thinking before doing a PR.

So this specific PR is done :)

I tested a reports fetching KPIs from 3 others subreports : test ok
Fantastic :)
