master: replace always_center_master with slave_count_for_center_master (#8871)

- Replaced boolean config parameter `always_center_master` to an integer value `slave_count_for_center_master` for more control on when to center master window.
- Also updated configuration parameter, type, description and related internal variable.

New description: **when using orientation=center, make the master window centered only when at least this many slave windows are open. (Set 0 to always_center_master)**

This effects center orientation of master layout.
Now, user can control when the master window would be centered
