Create schemas for API call and response

[jolevesq]

We should create a scheme that explain all queries

• Query sent to any of the API
• Query sent to our AWS API
• Response sent by any of the API
• Response sent by out API after parsing

There are two sets of schemas inside the repertory 'schemas' as well as in the AWS S3 bucket. those set are:

• Api. Two schemas are inside this section.
  • in-api-schema. Defines the rules to validate the application's url parameters as well as the options for 'available services'
  • out-api-schema. It defines the mandatory fields to make any returned feature valid, the constrains for numeric fields, and finally the valid services available.
• services. This branch contains the schemas for several services. Some are available, some might be in the future.
