builtin/maintenance: make the geometric factor configurable

Browse Source 
The geometric repacking task uses a factor of two for its geometric
sequence, meaning that each next pack must contain at least twice as
many objects as the next-smaller one. In some cases it may be helpful to
configure this factor though to reduce the number of packfile merges
even further, e.g. in very big repositories. But while git-repack(1)
itself supports doing this, the maintenance task does not give us a way
to tune it.

Introduce a new "maintenance.geometric-repack.splitFactor" configuration
to plug this gap.
