update all_inputs_test.json to not use None/null/[] for any inputs and switch to multiple outages model

None and empty lists get filtered out before being sent to REopt Julia package so for these we aren't actually testing that the names match. Should also switch from sending outage_start_time_step and outage_end_time_step to outage_start_time_steps, outage_durations, outage_probabilities, and min_resil_time_steps because these will be used by the v3 web tool. Would also be good to add something like "new inputs have been added to all_inputs_test.json" to the PR checklist.
