Refactor Directory structure

[YJDoc2]

Apologies for the big PR, but major of the changes are moved files.
This PR does some needed refactoring of directory structure, which will make it easier to understand and work on youki.

Major Changelog :

• created a dir integration-tests which will hold all integration tests, including oci-tests and its rust port, and later containerd etc.
• moved rust-integration-tests, runtimetest and test_framework from /crates to integration_tests/rust-integration-tests, as those do not belong to youki crates, and are better fit in the integration tests
• added scripts dir, where all the scripts including build script and script to run the integration tests will reside, this will make it easier to modify and run tests and build from a single point
• moved the oci-tests submodule from /integration_test to /integration_tests/oci-runtime-tests

This PR will form the first step for #601 , and does not complete it. I made this PR, as even by itself it is quite big, and I did not want to make the review more hard. After this is merged, the next steps in separate PRs will be :

• Improve scripts and makefiles . This PR adds scripts and makefiles just to make it work with CI. They are still a bit cumbersome to use manually. I will make another PR which should make it easier to manually use.
• Update the docs. Even though no code is changed, the docs need to be updated for new directory structure and scripts. This will also need its own separate PR.

When testing on my own fork, I noticed that the oci-integration-tests were failing, but not because of changes I made, but because one of the go tests was failing. Adding its link here, in case the same happens in this PR : https://github.com/YJDoc2/youki/runs/5091082926?check_suite_focus=true

@utam0k Apologies for such a big PR 😓 😓 , but most are moved files. Take a look whenever possible for you, and let me know if any changes are required.

Thanks :)

I'll check this PR next my holiday! But it seems this PR has conflicts. Can I ask you to solve it?

[YJDoc2]

Hey, no issues, take your time :)
I am working on why the integration tests are failing, after that I'll also solve the conflicts, so if there are any other commits by then and other conflicts, those will get solved as well.
Thanks :)

It would be nice if the make command could work from the top of the directory, is that possible?

[YJDoc2]

Hey @utam0k finally the CI is done 😅
Please take a look :)

[utam0k]

@YJDoc2 Can I ask you to update the README and resolve conflicts since the path to build.sh has changed?

[YJDoc2]

@utam0k please take a look :)
I feel even though this does complete directory refactor, the commands to build and run tests and youki can use a lot of improvements, as in this PR, they are pretty hard to use. After this I'll be working on that.

Hey @utam0k I have updated the readme and docs tutorial, please check
Also Currently there are conflicts, but what I feel is :
If we merge this one first, then there will be a lot of issues for PRs which are open like #758 etc.
I do not mind waiting till they are merged, and then resolving conflicts on my side.
Let me know 👍

[YJDoc2]

Hey, the conflicts are resolved, the CI is passing, and currently there are no other PRs open!
Please take a look 👍 😄
