Create a settings page for Apinf configuration options

[bajiat]

For organizations to host Apinf as a service, they need an easy way to configure the settings like mailgun. Create a settings page to hold current and future configuration options as well as a collection to store the configs.

Research

• Look for existing settings/ configuration pages in open-source Meteor projects
• Look for configuration page examples in other web applications
• Create a design document and list the solutions you found

Design

• Add a description of the configuration page to the design document
• Create one or more wireframes to demonstrate the intended design (do not skip this step)

Implement

• Create a collection to store configuration settings
• Create one or more templates to hold configuration forms
• Create a schema to define configuration settings
• Use AutoForm to build one or more configuration forms on the settings page(s)
