AppGroup Re-Create causes some Workflows to Hang

**Describe the bug**
On re-create, ApplicationGroups will delete their helmReleases to cleanup the namespace. If there is a forward workflow that is also running while this happens, it is possible that a race condition surfaces where the forward workflow upgrades a HelmRelease that is subsequently deleted by the previous reverse workflow.

**To Reproduce**
1. Create an ApplicationGroup based on bookinfo (or anything else)
2. Delete the ApplicationGroup
3. Create the ApplicationGroup immediately after deleting

**Expected behavior**
HelmReleases should be conisdered separate on different workflows and sectioned off from other HelmReleases. Perhaps we give a unique identifier to HelmReleases from previous workflows to keep this overlapping from happening?

Start by tracing ApplicationGroup deletion and recreation alongside the HelmRelease cleanup and upgrade paths. Reproduce the race with the bookinfo ApplicationGroup and overlapping workflows. Done means HelmReleases from concurrent or successive workflows cannot delete or upgrade one another, and the workflow completes without hanging.
