This patch provides the Insertion time of an index operation.
This information is useful to the administrator for reorganizing the indexes
based on the insertion time.

Quick review:

Applies to Head.
Regress test is passed.
Coding is fine.

Minor comments:

There is no need of printing the index insertion time as zero in case
of hot update operations.
Please correct the same.

Add the documentation changes.
