[PR #5867/b1d94385 backport][stable-6] apt_rpm: add clean, dist_upgrade and update_kernel (#6233)

apt_rpm: add clean, dist_upgrade and update_kernel (#5867)

* clean performs apt-get clean.

* dist_upgrade performs apt-get dist-upgrade.

* update_kernel performs update-kernel to upgrade kernel packages.

* update_cache, clean, dist_upgrade and update_kernel can be used with and without specified packages.

(cherry picked from commit b1d94385ae)
