iNN-Reach Settings: Manage INN-Reach Paging Slip Template for Central Server

Purpose:

Provide an interface in Settings to create and manage INN-Reach paging slip template on a per-central server basis.

User story statement(s):

As a FOLIO system administrator, I want the ability to create an INN-Reach paging slip templates for each configured central server connection, so that INN-Reach paging slips can be customized for each central server connection

Scenarios:
 # Scenario:
 ** Given an settings item "INN-Reach paging slip templates" under Settings > INN-Reach > Circulation settings (changed from current "Circulation mappings")
 ** When the user clicks on the settings item
 ** Then a central server selection drop down is presented
 # Scenario:
 ** Given the central server selection dropdown
 ** When the user selects a central server from the menu
 ** Then an existing template for the selected central server is retrieved and presented in detail view (a la staff slips in Circulation settings) OR an empty form is presented
 # Scenario
 ** Given the empty form scenario
 ** When the user fills in one of the fields
 ** Then the "Save" button becomes active
 # Scenario
 ** Given the "Save" button is active
 ** When the user clicks the button
 ** Then the template is saved (created)
 # Scenario:
 ** Given an existing configuration
 ** When the user selects the central server
 ** Then the populated form is presented

Other Information:

Refinement questions:
 * Where/how to store the templates
 * Should template objects use the same basic schema as staff slips
