REST service to update the content of a specified Rasa regex example

[turnerrainer]

AS AN Architect I WANT TO have a REST service to update an existing Rasa regex example SO THAT there wouldn't be any duplicate services for it

Acceptance Criteria

• [x] Use POST endpoint /rasa/regex/update-example to update a new Rasa regex example
• [ ] Apply changes on Rasa data/regex_nlu.yml as input
• [x] Apply changes to a specified regex
• [x] Apply changes to examples based on exact match

Examples

data/regex_nlu.yml

Input

version: "3.0"
nlu:
- regex: asukoht
  examples: |
    - abja[- ]paluoja
    - antsla
    - elva
    - haapsalu

- regex: nimed
  examples: |
    - büro
    - kratt
    - bürokratt

Output after making a request to update "antsla" to "[Aa]ntsla" within entity "asukoht"

As per @ExiRain suggestion, the current solution should be re-written to only overwrite the values that are currently selected to be changed, instead of overwriting the whole content of the file.

Working, but could be optimized. In Acceptance Testing but should be refactored later.

Pull requests: 264 258 Currently working, but working on optimisation (currently it requires entire array to replace existing, which is not best way, new solution would require only name of regex and old value + newvalue of example, which in total 3 values to update examples)

BUG - Unable to add regexes.

Unable to add regex examples.

Blocked because of #325. When adding new regex examples is possible, then we are able to test updating.

Seems to work as intended!
