Move big objects located at some of the commits to Git LFS

[lolski]

The git history contains large files which slows git operation. This diminishes developers productivity and we should move these big objects into Git LFS.

First, we'll need to identify what those objects are and in which commits they are located.

Second, remove them from the commit (maybe by using https://rtyley.github.io/bfg-repo-cleaner ?) and move them to git LFS.
