controller: Extend time before automatic resource cleanup

[ecpullen]

If a test with resources is created and the test is restarted, there is a chance the controller will mark resources with DestructionPolicy::OnTestSuccess for deletion.

Dod: TestSys should not have problems restarting an errored sonobuoy test. This can be reproed by launching a conformance test cargo make TESTSYS_TEST=conformance and restarting the test after it has started. I may need to be tested a few times since this is an intermittent issue.
