Service - Suspend Account Action

[eaglet]

As an Administrator I need A way to suspend an account So that I could stop a customer from generating new orders

Assumptions:

• We have a data model
• SQLAlchemy will be used to persist the data
• There is a status field could be set to "disable"
• The new endpoint calling /customers/{id}/suspend

Acceptance Criteria:

Given - The suspend endpoint
When - We invoke `/customers/{id}/suspend`
Then - The customer with that ID should be suspended 
And - The status filed in the database should be set to disable
