Why I did it
Support to use symbol links in platform folder to reduce the image size.
The current solution is to copy each lazy installation targets (xxx.deb files) to each of the folders in the platform folder. The size will keep growing when more and more packages added in the platform folder. For cisco-8000 as an example, the size will be up to 2G, while most of them are duplicate packages in the platform folder.
How I did it
Create a new folder in platform/common, all the deb packages are copied to the folder, any other folders where use the packages are the symbol links to the common folder.
Why platform.tar?
We have implemented a patch for it, see #10775, but the problem is the the onie use really old unzip version, cannot support the symbol links.
The current solution is similar to the PR 10775, but make the platform folder into a tar package, which can be supported by onie. During the installation, the package.tar will be extracted to the original folder and removed.
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.

# 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.

Why I did it
Provide onie image install verification
How I did it
Add devices folder based on platform_asic and check if current platform inside the list
How to verify it
In onie env, install a bin image which differs the running platform's ASIC. For example;
install sonic-broadcom.bin to mellanox ASIC platform
install sonic-vs.bin to broadcom ASIC platform
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
```
closes#6267
#### Why I did it
* To fix#6267
#### How I did it
* Fixed installer scripts
#### How to verify it
1. Write invalid SONiC version to sonic_version.yml
2. Run SONiC-To-SONiC update
