Add detailed_job_info

[t-reents]

Adding the command to retrieve the detailed_job_info. Since this was missing until now, jobs run via HQ didn't have the detailed job info. I only parse the output of hq job info <id> (transformed into a one-line json using jq) for logging purposes. The data can be analyzed with json.loads().

Hi @t-reents, can you describe the use case how you use the return value of detailed_job_info, I thought it only consumed by scheduler.parse_output which we not yet implement. Once we have it, it will read from detailed_job_info and get information such as walltime exceed or OOM error and set the exit_code to calcjob, is this what you have in your code?

Hi @unkcpz, you are right. As I also mentioned in #24, ideally we also implement parse_output here. This PR was just to implement at least the detailed_job_info command, since we were considering to use HQ for the hero run. We wanted to have at least the raw info when calling get_detailed_job_info() on a CalcJob, potentially enabling some kind of debugging afterwards

Make sense @t-reents
Can you move the implementation to the end where I put a TODO in the function, now it has to methods with same names.
Besides it, all good to me, we can then merge it.

Thanks, I thought that I removed it. Now it's done
