Adds scripts/calculate_release_shas.py to print the versions, and updates tool versions. Consolidates target-determinator logic with the other tool logic. This is also intended to make it easier to add more tools.

"""Computes the potentially differing rules from some git commit.
|
|
|
|
Wraps the "target-determinator" Go program here:
|
|
https://github.com/bazel-contrib/target-determinator
|
|
|
|
The purpose is to compute the potentially impacted set of targets from some
|
|
provided Git commit to the current checkout.
|
|
|
|
This script will ensure a cached version of the latest release is available, and
|
|
then forward a limited set of flags to it. This script also filters the
|
|
resulting targets using `bazel query` to make it the most relevant list for
|
|
continuous integration.
