[WIP] Network intervention simulation

[benoitblanc]

This pull request aims to add some features for the user to simulate network incidents :

• network leakage
• network interruption
• network pollution

[bogdanvaduva]

You've used my proposal for adding network path capabilities to QWAT. The pipe_reference table should be explained a little bit more, it needed geometry because otherwise we couldn't have a real path shown. The pipe_reference table must be kept up to date because otherwise the path could be different from what the user sees.

@benoitblanc Does this has a connection with what kind of network simulation software? Does this comply with the SIA405 water datamodel (Hydraulischer_Strang, hydraulischer_Knoten)?

[3nids]

does it fix #171 ?

[ponceta]

Since there are only deltas, the network simulation are not initialized when initializing from scratch :

https://github.com/qwat/qwat-data-model/blob/master/init_qwat.sh

Please add the necessary files (same content as the deltas) and code adaptation to make it work for new users of TEKSI water module.

[benoitblanc]

@ponceta I have added code from deltas to data-model and init_qwat.sh

[ponceta]

Something doesn't please the CI. Is it possible that the delta initialize the functions but does not run these and therefore does not create the tables or vice versa?

@benoitblanc could you rename the deltas to 1.4.0_XXX

[benoitblanc]

@ponceta I have renamed deltas to match v 1.4.0

[ponceta]

Tests are fine, upgrade is fine.

We have issues on scalability tests and scalability tests multithreaded :

https://github.com/qwat/qwat-data-model/actions/runs/3912471610/jobs/6687155084#step:7:2289

Could you have a look at it? (It is probably due to our last merge of fk_distributor inheritance and should maybe be adressed in another pull request )

@olivierdalang can we have a red light when scalability tests are not working fine?
