Use local data for summing of groups buckets

[NitayRabi]

• Until we use allocations service we should support local allocations.
• Currently given allocations is summed and displayed in pre_sale_allocation prop of group coming from spark.

Sum allocation for group both in PresaleAdmin and PresaleLeader using adminallocations (data stored locally in our db).
Sums should only address data which is published.
Components -

Admin - Screen for giving pre sale allocations.

Leader - Screen for group leaders to allocate to group members.

adminallocations model
(pay attention to allocation type and publication date)
