Ele 327 create report endpoint

[IDoneShaveIt]

Created an endpoint for report generating via webapp API.

• Split APIs into APIs and fetchers.
• Moved API logic from data monitoring report to report API.
• No new logic - only renaming and moving files around

ELE-327 Create report endpoint

DoD:

• This endpoint should return the same json as the one we inject today to the html
• Endpoint should not run CLIs, therefore we should make it fast enough by:
  • Running the edr code as python code and not the CLI
  • Running dbt-core with python instead of running a sub-process (PythonDbtRunner)
