Add a new resource_table_schema_infer action

[amercader]

This action returns the inferred Table Schema from an existing resource file (upload or link)

Details:

• Name:
• Auth: Should defer to resource_create
• Params:
  • resource_id: a resource uuid
  • store_schema: a boolean flag to determine if the inferred schema should be stored to the resource (using resource_patch). Defaults to True (I have no strong opinions either way)
• Output: let's return the generated Table Schema in a separate key in case we need to add extra fields to the response: {"schema": <Table Schema descriptor>}
