Notable change

Debian behavior is to ignore any existing value of the PATH environment variable when launching bash and set it to a predefined value. This makes it impossible to modify the PATH in the Dockerfile. Alpine's approach (taken from Arch Linux) is to append the path components to any existing PATH value, allowing users to set a preferred path, but still ensuring that all expected/required directories are included in PATH to start.

In this release, we follow Alpine's strategy under Debian. This means that if you were previously setting PATH in your Dockerfile, it was being ignored, but now it will be respected (but may be appended to). So in cases where you have different versions of binaries with the same name in different directories (e.g. different terraform versions in /bin, /usr/bin, and/or /usr/local/bin), which binary gets executed may change in this version.

This brings the Debian and Alpine behavior of Geodesic into alignment with respect to handling PATH.
