Adding git lfs support

Synced from Eclipse Che issue

https://github.com/eclipse/che/issues/20642

Summary

Hi,

using the devfile below I am setting up my WS.
The repo gets cloned but the git-lfs stored files only contain references (theia-editor only contains git, not git lfs)
How could I install git lfs into the theia-editor and would that fix it? (It seems to be a javascript image)
Or would I have to install it into a different image?

Thanks in advance.
