Reduce the disk space taken up during bootup and runtime.
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.

* Don't create var-log.ext4 if we're storing logs in memory
Signed-off-by: Saikrishna Arcot <sarcot@microsoft.com>
* Run tune2fs on the device containing /host to not reserve any blocks for just the root user
