maintenance: add incremental-repack auto condition

The incremental-repack task updates the multi-pack-index by deleting pack-
files that have been replaced with new packs, then repacking a batch of
small pack-files into a larger pack-file. This incremental repack is faster
than rewriting all object data, but is slower than some other
maintenance activities.

The 'maintenance.incremental-repack.auto' config option specifies how many
pack-files should exist outside of the multi-pack-index before running
the step. These pack-files could be created by 'git fetch' commands or
by the loose-objects task. The default value is 10.

Setting the option to zero disables the task with the '--auto' option,
and a negative value makes the task run every time.

positive value implies the command should run when the number of
loose objects is at least the value of `maintenance.loose-objects.auto`.
The default value is 100.
maintenance.incremental-repack.auto::
This integer config option controls how often the `incremental-repack`
task should be run as part of `git maintenance run --auto`. If zero,
then the `incremental-repack` task will not run with the `--auto`
option. A negative value will force the task to run every time.
Otherwise, a positive value implies the command should run when the
number of pack-files not in the multi-pack-index is at least the value
of `maintenance.incremental-repack.auto`. The default value is 10.
