Reverts #431

I have already done a preliminary review for you, and I hope to help you do a better job.

Based on the pull request title and description, it seems that this is a revert of a previous change that was made in PingCAP-QE/artifacts#431.

Looking at the diff, it seems that the changes in this pull request are related to updating packages in various Dockerfiles. The changes involve updating the date and version number of the packages that are being installed, as well as removing the removal of the /var/cache/yum directory after installing packages.

As for potential problems, it's difficult to say without knowing the context of the previous change that was made in PingCAP-QE/artifacts#431. If that change was made to optimize the size of the Docker images, then this revert may result in larger image sizes.

If the changes in this pull request are deemed necessary, then one suggestion could be to investigate alternative ways to optimize the size of the Docker images without removing the /var/cache/yum directory. Alternatively, if the changes in PingCAP-QE/artifacts#431 were deemed unnecessary, then the revert in this pull request may be appropriate.
