Curl to recover-id-object

[lassemand]

Purpose

As part of the reporting in https://docs.google.com/document/d/1CxI5-c0bRdJm0C0THE18xh4DoTOLPRNn0Su2qWZMCrM we need to report an issue given a non successful recovery occurs. The output channel here is slack, and they use callbacks. Hence we need to use a callback which I would like to use curl for.

Changes

Install curl to dockerimage
