Unnecessary padding around alert atop debug pod terminal

Description of problem: there is unnecessary padding around the alert at the top of the debug pod terminal.

Steps to Reproduce:

1. Create an crash looping pod by creating the default `example` pod using the `Create pod` button at the top of the Pods list page
2. Once the pod has a `Status` of `CrashLoopBackOff`, click `CrashLoopBackOff` so the popover appears and then click the `Debug container httpd` link within the popover
3. Note the alert at the top of the resulting `Debug httpd` page has unnecessary padding of 10px on all sides.
