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' .
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.
