Remove big files from git history

[deepakgangwar]

Sometimes very big files are committed and can not be pushed any commit due to this previous commit so steps to remove such files and changing the git history should be included.
Either the native git commands or bfg will be a good option.

I agree! A PR for this would be great. :)

I did a writeup of this exact problem here, when migrating away from git-lfs, using bfg:
