Report Error via JSON interface when Project repository is not accessible

[smarr]

Currently, my python client will just timeout on sending data to http://...result/add/json/ when the project's repository (git in my case) happens to be not accessible. The results are then lost, and no error indicating that problem is returned.

I haven't looked into the code, but for me it looks that codespeed is blocking on that repo access to get a commit or so, and then the result reporting gets blocked as well.

Would be good if that issue could be reported to the JSON client, or if results could be even delivered when the repo is not accessible/the settings are broken.
