Modal confirmation dialogs should handle enter/return key similar to esc/escape

Description of problem:

When the user is deleting a resource (for example a Deployment) the web console opens a confirmation dialog which could be closed with the ESC key.

It would be great if the user can confirm the request also with the ENTER key. This is a common pattern in native applications and in high quality web apps as well.

When the user tries to delete a complete application its required that the user enters the application name. In the case that the confirmation dialog contains such a input field (1 input field) this field should be focused automatically.

Prerequisites (if any, like setup, operators/versions):

None

Steps to Reproduce

1. Open the Developer perspective
2. Create a Deployment with Add > Import from container
3. Try to delete the Deployment..
4. Try to delete the Application...

Actual results:

1. When the Delete Deployment confirmation dialog opens ENTER does nothing.
2. When the Delete Application confirmation dialog opens the focus was not set..

Expected results:

1. When the Delete Deployment confirmation dialog opens ENTER should confirm this.
2. When the Delete Application confirmation dialog opens the input field should be focused.

Reproducibility (Always/Intermittent/Only Once):

Always

Build Details:

All versions of 4.5 and 4.6
