GSLUX-744 Feature measurements

JIRA issue

https://jira.camptocamp.com/browse/GSLUX-744

Description

PR calculates and updates the measurements of a drawn/edited feature.

It also adds two dependencies:

• cypress-real-events: for better testing of openlayers actions on the map
• eslint-plugin-no-only-tests: to prevent forgetting onlys in test suites

To-dos:

• Get elevation for points
• Calculate radius and adapt length and area calculation for circle (once it is managed as a circle geometry) => depends on GSLUX-743 and will be done in GSLUX-743: Modify circle geometries #159

Working great thanks (did not test elevation for point because I tested the github pages, but code looks ok).

Maybe extract formating (in feat.measurement helper or from measurements.utils) to have the code for formatting text in the same place?
