v6.4.0

Updated Tests

-apps/crashing.go

• There are two fixes to test app crashes:

1. The id checking for recovery was giving false positives because the post-crash ID was returning an error message which happened to differ from the pre-crash app's ID. It turns out that that IDs are reused on cf-for-k8s but change for cf-deployment.
2. The two different infrastructure's IDs match different specific regular expressions, so a more general one handles both cases.

• cf-for-k8s is waiting for a new release of eirini that will handle app.crash events, so that test is skipped for cf-for-k8s but the recovery tests can be run.
