Move existing cypress tests into metasfresh-e2e repo

[metas-ts]

@siemiatj this repo's gh7-e2e branch now contains

• the cypress folder
• the cypress.json

from metasfresh-webui-frontend.

It also still contains the things it used to contain, e.g. the Jenkinsfile that builds an e2e docker image by cloning metasfresh-webui-frontend. Please make cypress work in here. Feel free to edit, move around, rename etc whatever you need to
