What Does This Do
Implements logic for "unshallowing" a shallow Git repository.
The code checks whether current repo is a shallow one and if so, attempts to refetch the commits data from the server for the past month.
Motivation
CI Visibility's Intelligent Test Runner requires Git data in order to work: the tracer has to upload Git pack files to a backend endpoint.
Many CI providers clone their repositories with a shallow clone, which means there is no commit history. In those cases, sending a packfile to the backend would not be the correct choice since we would generate a packfile with a single commit instead of the necessary payload, therefore polluting the state of the backend.
