* Remove apt package lists and make macro to clean up apt and python cache
Remove the apt package lists (`/var/lib/apt/lists`) from the docker
containers. This saves about 100MB.
Also, make a macro to clean up the apt and python cache that can then be
used in all of the containers. This helps make the cleanup be consistent
across all containers.

Why I did it
Unify the Debian mirror sources
Make easy to upgrade to the next Debian release, not source url code change required. Support to customize the Debian mirror sources during the build

How I did it
How to verify it
# Why I did it
Reduce the disk space taken up during bootup and runtime.
# How I did it
1. Remove python package cache from the base image and from the containers.
2. During bootup, if logs are to be stored in memory, then don't create the `var-log.ext4` file just to delete it later during bootup.
3. For the partition containing `/host`, don't reserve any blocks for just the root user. This just makes sure all disk space is available for all users, if needed during upgrades (for example).
* Remove pip2 and pip3 caches from some containers
Only containers which appeared to have a significant pip cache size are
included here.
