Jason Tedor 5a03eb91e6 Add precise logging on unknown or invalid settings
Today when logging an unknown or invalid setting, the log message does
not contain the source. This means that if we are archiving such a
setting, we do not specify where the setting is from (an index, and
which index, or a persistent or transient cluster setting). This commit
provides such logging for the end user can better understand the
consequences of the unknown or invalid setting.
