If it is run during image install, it's not guaranteed that the
installation environment will have tune2fs available. Therefore, run it
during initramfs instead.

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.

(cherry picked from commit 5617b1ae3e)
This improvement reads current SONiC version directly from `/proc/cmdline`.
it supports `grub/aboot/uboot` bootloaders.
**Code snippet**:
```bash
cat /proc/cmdline | sed -n 's/^.*loop=\/*image-\(\S\+\)\/.*$/\1/p'
```
**Description**:
```
-n don't print lines
s substitute
^.* matches anything before the <image_version>
loop= matches <loop> kernel parameter
\/*image- matches <image_version> prefix
\(\S\+\) matches <image_version> group and assigns it to \1
\/.*$ matches anything after the <image_version>
\1 replace everything with <image_version>
p print it
```
