Add note about how each partition's default value is treated, into the doc.

Browse Source 
Column defaults may be specified separately for each partition.
But INSERT via a partitioned table ignores those partition's default values.
The former is documented, but the latter restriction not.
This commit adds the note about that restriction into the document.

Back-patch to v10 where partitioning was introduced.
