[Haizea] SlotTable in at_timestep method of AccountingProbe

[Borja Sotomayor]

Hi,

You could do it this way, but that's not a change that I would commit
to Haizea, since I want to keep the accounting probes as decoupled as
possible from the core code.

To get the current time, use the get_clock() function in haizea.common.utils

Adding the slottable as an attribute of AccountingDataCollection seems
like overkill. You can access it from at_timestep through
lease_scheduler.slottable.

Cheers!
