[Enterprise Search] MongoDB Connector cypress test. (#155886)

## Summary

Add automated tests via Cypress for MongoDB and Web Crawler happy paths.

Tests are quite basic and covers only adding simple one time sync paths.
Fill in the `cypress.env.json` with the credentials before running.
Mongo specs will run only against a local environment (via `./cypress.sh
dev`) as connector has to be running locally as well.
