Allow Hub operator staff to set up thresholds for notification of Participant staff

[PaulMakinMojaloop]

As a member of Hub operator staff, I want to facilitate notifications for Participant staff who have provided contact details that are registered with the Participant's details at the Hub.

Prerequisites:

1. From the list of registered contacts, one must be selected to receive notifications
2. All contact details for that individual must be completed.

Actions

For each currency the Participant is operating in, the hub operator staff member must:

• Set a minimum value of available liquidity
• Set a percentage of NDC

for which notifications will be generated.
