Purpose
=======
We want to allow different approvals for allocations and leaves of a same type.
e.g. In case of compensation days, a manager would approve the
allocation request, but would later not approve leave requests.
Specification
=============
Allocation modes
----------------
No change here except renames.
1. No limit (employee doesn't need an allocation to request a leave)
2. Allow employee requests
3. Fixed by Time Off Officer
Allocation approval
-------------------
A radio field to choose the approval mechanism
appears if the employee is allowed to request an allocation.
The following approval modes are possible:
1. Time Off Officer
2. Employee's Time Off Manager (leave_responsible_id)
3. Employee's Time Off Manager and Time Off Officer
These options are the same as leave approval options
(except the missing "No Validation").
If option 1 or 2 is selected, a o2m field should
allow to select which Time Off Officer is responsible
for approving those allocations.
Allocation approval policy is the same as the leave approval policy.
