Now toggle when deleting a pod

[arthurdarcet]

Is your feature request related to a problem? Please describe.
Deleting quickly a pod that has been created with a very long grace period to free up resources that are needed immediately elsewhere

Describe the solution you'd like
In the "Delete pod" dialog, add a Now toggle (next to Propagation and Force) that sets the grace period to 1 (NowGrace)

Describe alternatives you've considered
change the "Force" toggle to a three way switch Force / Now / Normal ?

Thanks!
