Document CRD-related functionality

[olensmar]

Monokle has a bunch of features related to CRDs (apart from showing CRDs in the navigator) - these should be documented accordingly:

Monokle "learns" any discovered CRDs (files, clusters, previews) and uses their schemas to

• add corresponding sections in the Navigator
• allow users to create discovered resource kinds in the "New Resource" dialog
• provide schema validation and context-sensitive help/popups for corresponding resources in the source editor
• render Forms in the form editor

@devcatalin anything else?

Here is the initial page in the docs that's covering the CRD-related functionality: https://kubeshop.github.io/monokle/resource-crds/

Wondering if there is somethings else to be added to this

[olensmar]

perhaps mention how CRDs are handled/visualised in the new Cluster View?
