DWaveSampler docs for the returned SampleSet

[arcondello]

Currently the SampleSet returned by the DWaveSampler contains information in the info field. E.g.

>>> DWaveSampler().sample_ising({0: 0}, {}).info
{'timing': {'total_real_time': 7757,
  'qpu_access_overhead_time': 824,
  'anneal_time_per_run': 20,
  'post_processing_overhead_time': 315,
  'qpu_sampling_time': 164,
  'readout_time_per_run': 123,
  'qpu_delay_time_per_sample': 21,
  'qpu_anneal_time_per_sample': 20,
  'total_post_processing_time': 315,
  'qpu_programming_time': 7593,
  'run_time_chip': 164,
  'qpu_access_time': 7757,
  'qpu_readout_time_per_sample': 123}}

the docs for the DWaveSampler should explain where to find this list. Right now it only contains timing so perhaps should link to timing-related fields?

The most common occurrence of this for me is the following. I want to access a specific field in a SampleSet returned from sample_qubo. I go to the documentation for sample_qubo (https://docs.ocean.dwavesys.com/projects/dimod/en/latest/reference/generated/dimod.Sampler.sample_qubo.html#dimod.Sampler.sample_qubo) and see that a SampleSet is returned. I click on SampleSet (https://docs.ocean.dwavesys.com/projects/dimod/en/latest/reference/sampleset.html#dimod.SampleSet) and can't find the information I want about accessing the qpu_access_time or any of the other sampler specific fields. I end up running my program and printing out the entire SampleSet object to see what each field is named and what's there, then rerun my program to get that item.
