    Change the python interpreter discovery mode.

    Current default mode for the python interpreter discover inansible 2.8 is
    auto_legacy. This patch changes the mode to auto, the biggest difference
    respecting auto_legacy is 'If no entry is found, or the listed Python is
    not present on the target host, searches a list of common Python interpreter
    paths and uses the first one found' [0].
    Currently, it has been observed some issues with the
    discovered_python_interpreter fact not getting updated on specific scenarios
    (for example, when upgrading the node from RHEL7 to RHEL8). This change is
    expected to improve this situation.
