disable housekeeping messages for render

[tejal29]

Relates to #5711 ,

With the new changes to "update check" (#5741) and metrics,

1. update check and metrics prompt will happen on every run unless they are disabled.

This might break skaffold render if it's being used for the first time. This is true for CI usecase.
Since skaffold render spits out yaml, we should be disallowing any house keeping messages similar to skaffold diagnose
