[Bug]: Precheck flight should give warning/error message if running in cloud environment.

Error:
  0: Fluvio cluster error
  1: Preflight check failed

Cluster error is too generic. It should guide me to a resolution.
For example, it could say

 [err]: your profile points to cloud
      Try switching profile `fluvio profile switch minikube`

Preflight check requires admin access to Kubernetes clusters. Before running cluster any sub commands check for k8 access for profile and warn them this requires Kubernetes access.

Will add a --fix flag to fluvio cluster check to try to fix recoverable checks.

Will update fluvio cluster check --help to indicate that user needs access to Kubernetes cluster and have the Kubernetes context set.

Will update fluvio cluster check to warn user that Kubernetes cluster is required

Will add a message to run fluvio cluster check --fix if a recoverable error is raised.
