OCPCLOUD-2642: manifests-gen: Allow overriding kustomize component path

[nrb]

This PR adds the ability to locally override the path for Kustomize components within a CAPI provider repository.

This is required for openshift/cluster-api-provider-azure#322 so that the Azure Service Operator's Deployment arguments can be overridden to ignore handling CRDs.

Adding that modification directly in the Go code here would create a tighter coupling between this repository and the CAPZ one, and would be less flexible for future scenarios.

Also added a README file to explain some assumptions in the code base and document overriding the Kustomize component path.
