Additionally, provide ability to opt-out of the .go-version and use a
custom one via env vars: FORCE_HOST_GO and GO_VERSION.

# The version present in the .go-verion is the default version that test and build scripts will use.
# However, it is possible to control the version that should be used with the help of env vars:
# - FORCE_HOST_GO: if set to a non-empty value, use the version of go installed in system's $PATH.
# - GO_VERSION: desired version of go to be used, might differ from what is present in .go-version.
# If empty, the value defaults to the version in .go-version.
