Provide preconfigure pipeline / config

[beevelop]

In the current (and great) v3 version of Rasa-UI the config field is empty by default when creating a new agent. For novice users of Rasa this might be quite confusing. Therefore it would be awesome to provide a sane default value. Something like e.g.:

pipeline:
  - name: WhitespaceTokenizer
  - name: CountVectorsFeaturizer
  - name: EmbeddingIntentClassifier
  - BILOU_flag: true
    name: CRFEntityExtractor
    features:
      - [low, title, upper]
      - [low, bias, prefix5, prefix2, suffix5, suffix3, suffix2, upper, title, digit, pattern]
      - [low, title, upper]
  - name: EntitySynonymMapper

Thanks for the feedback and good idea. With this pipeline you suggested, are there any dependencies on Rasa? (e.g. Spacy or something similar)?

This configuration is quite similar to the default supervised_embeddings: https://rasa.com/docs/rasa/nlu/choosing-a-pipeline/#section-supervised-embeddings-pipeline This one does not rely on Spacy and is language independent.

It might be quite helpful to add the following link near the config textarea for reference: https://rasa.com/docs/rasa/nlu/choosing-a-pipeline/
