…use new platform router (elastic#56972)

* [ML] change import endpoint call to fileupload plugin, update file analyzer endpoint

* [ML] add apiDoc annotation

* [ML] AnalysisResult interface, remove url from apidoc.json

* [ML] delete import_data.js

* [ML] remove caching code, address PR comments

* [ML] file import

* [ML] apidoc

* [ML] schema validation
