From: Teng Long @ 2021-05-07  2:11 UTC (permalink / raw)
  To: git; +Cc: jonathantanmy, Teng Long

On the server, more sophisticated means of excluding objects should be
supported, such as commit object. This commit introduces a new
configuration `uploadpack.commitpackfileuri` for this.

This patch only pack the commit object, not including the that commit
and all objects that it references. This work will be done in a further
patch recently.

Similarly, there are related documents that will be included in
subsequent patches.
