After Python 2 is getting unsupported, new distros like CentOS 8 and RHEL8 have stopped providing 'python' package forcing user to decide which alternative to use by installing 'python2' or 'python3.x' package and then setting python alternative. This change is intended to make using python3 command as much as possible and use it as default 'python' alternative where needed. The final goals motivating this change are: - stop using python2 as much as possible - help adding support for CentOS 8 and RHEL8 Change-Id: I1e90db987c0bfa6206c211e066be03ea8738ad3f
