Convert cheatsheet documents to markdown (md) files

[diptangsu]

I think it would be better to have the cheatsheet documents as .md files instead of the corresponding language files.

It would be more readable and it would be able to present the documents in a better format.

I think that's a good suggestion. If this is still wanted then I would love to do it.

@mihir-1997 If you have the time to do this, feel free to try with one cheatsheet. :)

@LeCoupa I have converted kubernetes file to .md and sent you PR. Please review and let me know if any changes needed.

@LeCoupa Do we want to change all files to markdown format one by one?

[LeCoupa]

yes, this would be great! :)
