- What I did Change the flag error message for the docker app root command

- How I did it Set a custom FlagErrorFunction to the root command

- How to verify it

run docker app --unknown_flag should return
```
unknown flag: --unknown_flag
See 'docker app --help'
```
echo $? should return an error status code equal to 125
run docker app install --unknown_flag should return
```
unknown flag: --unknown_flag
See 'docker app install --help'
```
echo $? should return an error status code equal to 125
run docker app should return the usage message
