Delete without removing CRDs

[salotz]

I am debugging some things and I don't want to wait for the control loops to run to trigger events (e.g. authentication to helm repositories).

To do this I can delete the resources and re-create them. However, currently when I do timoni bundle delete ... it seems to try and remove CRDs which takes a very long time. This actually timed out for me.

It would be useful to have a flag to ignore deleting the CRDs when running delete for this kind of use case perhaps.
