Consumed energy output: instantaneous power might be cleaner about batsim HOT 3 OPEN

Commit 11df8f4 adds wattmin information from SimGrid as a temporary fix.

Using the current power computed by SimGrid should be better, but it does not seem possible with current forked SimGrid version.
@Shurakai's new energy plugin seems great to get it easily. Is it usable from MSG applications ?

Does S4U solve this issue?

Retrieving such information from SimGrid is not as easy as it seems.

Batsim is most of the time called at the end of a job, so the involved hosts are idle in the current power consumption. We could add a callback at the end of each computation (via s4u) but I feel that this is not really needed in our case.

Furthermore, the semantic of such power values in the _consumed_energy.csv is not so clear.
Only keeping time/energy measures might be easier to understand for users and sounder to use for analysis and visualization tools. For example, evalys only reads time/energy measures and retrieves the power information from it (figure below).

I feel like this issue should be closed.
