Reasons: First reason, `uploadpack.blobpackfileuri` supports to exclude a single object, but actually the object type can be not only a blob, so the name is inaccurate currently. Secondly, the name of the old configuration is not abstract enough, this make the furthur extension difficult. If do not change its name, to let different object types use different configuration names, the configuration items will be bloated and difficult to maintain, so the new configuration is more abstract in name. Configuation format diff: old: uploadpack.blobPackfileUri= new: uploadpack.excludeobject= The new configuration `uploadpack.excludeobject` not only supports to exclude a single object itself, but also to exclude related objects with it at once, the scope of exclusion is determined by the object type and the specified `` value in the entry. -Compatibility: Although a new configuration has been introduced, the old one is available to use and compatible with the new configuration.
