Ready condition check in generic UI

[nexus49]

Context

In today's implementation the generic UI the UI always checks for the Ready condition before allowing navigation to a given resource.

Desired behavior

• By default there should not be a ready check and you should be able to navigate to a resoruce immediately.
• It should be possible to configure a ready condition, only when this is configured the ui should check for it before allowing to navigate.
• It should be possible to configure a expression in the generic UI configuration for example by using a jmespath to either specify a certain condition or another field on the resource eg. .status.status
