Unless Sonar that wants you to replace "busId" by the constant BUS_ID in Reports, I am ok with the PR 👍

This is not a good idea. busID is used in the string template. It is better to be able to check visually that the parameter is same as the one in the template.

this PR should not have to deal with rounding.
rounding issue will be addressed by #1187.
Once we have new powsybl-core RC we will be able to finalize this PR

Good point. I'll add the need rc-core tag and see how the reports look like with the new core behaviour.

@jeandemanged Done. Note that #1187 applies only to testing. The underlying core PR powsybl/powsybl-core#3317, just allows to define variable formatters when tunring reports into Strings. The formatters may take advantage of the Unit. So I added a Unit to the new messages, when it makes sense.
