Dmitry Tantsur 3c78c29e94 Replace CentOS 7 images with CentOS 8 ... CentOS 7 uses Python 2. Although it's possible to install Python 3 on it, it not trivial with DIB. We should rather switch to a distribution where Python 3 is the default version. As a nice side effect, the CentOS 8 images seem smaller. The CentOS 7 job definitions are kept around since they're used on stable/train. Change-Id: I6b23da21eab19c69f7b070adff76b35e1752bf8d		2019-12-26 12:37:59 +01:00
