Task: Replace the maximum allowed number of nominations per nominator with a dynamic maximum based on the account's state (e.g. balance) by defining a typ NominationsQuota that returns the max number of nominations allowed for a given account.

Both the number of targets and nominators (and respective nominations) impacts the size of the snapshot, thus the size of the snapshot may become critically large if the number of votes per nominator are large. Thus, the number of voters that are taken for the election snapshot must be dynamic over the number of nominators and respective nominations.
