[docs] Add an upgrade note about MM threads

Some users configure MM threads to high values to work around the fact
that the MM was slow at scheduling tasks. This is now fixed in 1.4, so
this patch adds a note about this.

PS1, Line 38: It's generally recommended to keep a 1 to 3 ratio
Meaning, if I have 12 data directories, I should have 4 MM threads? If so, reword:

  Generally, the recommended ratio of MM threads to data directories is 1:3; operators of clusters above that ratio should be mindful of this when upgrading.


PS1, Line 39: clsuters
clusters
