OpenAPI spec import : create folders from tags

Currently, when a spec is imported, endpoints are stored in a folder tree structure based on the path: when multiple endpoints share the same path prefix, it is used as a folder in Yaak workspace. This makes the tree navigation difficult, especially because endpoints labels does not refer to their url, only to the endpoint summary.

Maybe a good option would be using “tags” value from spec to classify endpoints in a folder structure, similar the one displayed on Swagger or ReDoc UI.

The only downside would be that each endpoint may be “contained” in multiple tags, so the current Yaak structure could lead to duplicated endpoints (each one in a different folder)
