We need to support the accrual allocation for leaves.
This is a special type of allocations that adds some leaves to the
allocation every X amount of time worked.
This kind of allocations is especially used in the USA, but can also be
used in other contexts (eg: In Belgium we could allocate 20 days per
year for the legal leaves)
These allocations have support for :
* A max balance limit
* Going in negative (if set on the leave_type and the manager
approves the leaves)
* Removing the unpaid leaves from the quantity of days worked
* Setting an end date after which it does not allocate anymore leaves
