Reset AWG offset/gain in Qblox backend before start experiment (#377, QAE-751)
Explanation of changes
This MR adds a fix which resets the digital (AWG) offset and AWG gain of Qblox modules to a known value before starting an experiment. The setting to control this is located in the SequencerSettings and can thus be changed in the portclock parameters in the hardware configuration.
Note that this concerns only the AWG offsets and gains and not the I/Q mixer offsets and gains.
Motivation of changes
It was observed that, when (1) the current schedule does not touch the digital offset/gain and (2) a previous experiment did not reset the offset/gain to their (reasonable) defaults, the previous offsets and gains will show up when playing the current schedule. This behaviour is not how the sequencers were intended to be used, and this MR aims to fix that.
