[Evergreen-general] Upgrade path from 3.9.1 to 3.10.0?

[Jason Stephenson]

Hello, Linda!

It looks like the 3.9.1 to 3.10.0 database upgrade is missing from the 
3.10.1 release branch.  This means that it is likely missing from the 
3.10.1 tarball as well.

It does exist in the rel_3_10 and master branches in the git repository, 
so you could copy it from there.

I'll fix the 3.10.1 release branch and see if we can get an updated 
tarball released this week.

Cheers,
Jason
