Add a form editor for config maps

Hello team,

In OCP3 we had 2 styles of editors. A 'nice' one which seems to be the default, and then the YAML editor. You could go and open the Config Map with 'Edit' or 'Edit in YAML'. In OCP4 the 'nice' editor is gone and we have only the YAML editor (Monaco?).

Please, implement the 'nice' editor of Config Maps into OCP4 web console.
