Pass context through cmd and use RunE instead of Run

[inteon]

Pass context by calling cmd.ExecuteContext(ctx) and retrieving it using cmd.Context(). Also, call cmdutil.CheckErr only in main.go and use RunE and PreRunE to pass the error to main.go.

An example of cmctl check api -v4 --logging-format=json --wait=5m still working:

We do not want cobra to print the usage every time there is an error.
