Expected/desired behavior

The install of CAPZ relies on the natural available mechanisms for installation with ArgoCD versus the pre-sync sleep hook which points to sleep hook file.

This could be one or more of the following:

1. Sync-Waves
2. Progressive Syncs

Attempted to make this work by:

1. Setting readiness delay to 60 seconds
2. Setting cert-manager to sync-wave -1, CAPI-Operator to sync-wave 2, namespaces inside chart to sync-wave 3/4 See code comparison here

The cert-manager did see the 60 second delay and ArgoCD did wait for it to state it was ready before proceeding to try and install CAPI-Operator. Unfortunately, CAPI-Operator failed to install due to not getting the certs needed.
