Gate parameters in runcard description

[visagim]

Thus far we had "standard gates" defined in the runcard which mostly had the same parameters
eg.

  amplitude: 0.50
  phase: 0
  duration: 100
  shape:
    name: gaussian
    num_sigmas: 4

This is changing since we are adding gates like Drag and CZ which have different parameters (which might not be used at other gates) and do not have some others. Namely both Drag and CZ do not have a phase value (because for the Drag pulse this comes from the gate parameters higher in the stack at the circuit definition, and CZ is implemented via flux pulses which don't have/need a phase)
However, the parameters amplitude, phase, duration are always required.

Which parameters should we check always check for (eg. at gate_factory) and which should we instead check separately at each gate definition (eg. in the translate method applied at each gate) ?
