Add install order

[tylerauerbeck]

Occasionally the helm install will fail because the CheCluster is applied before the CRD is available. Need to update the chart to be smart enough to apply in the appropriate order.

Hey @tylerauerbeck , I got hit by his 100% of the times I have tried to install the chart ...
Not sure why, never got it right. Also it is quite hard to debug this because the dry-run does not work due to the "lookup" function...

I haven't found a way to specify the order in which manifest are rendered/process...
I will propose to separate this in two charts, install any operator first, and then the rest of the content as suggested here: https://helm.sh/docs/chart_best_practices/custom_resource_definitions/#install-a-crd-declaration-before-using-the-resource

Thoughts?

@jtudelag I think that's the route to go for right now (and then just have two seperate helm install commands). There are a few other ideas I'm working on right now, but will need some time to prove them out.

@jtudelag Actually I came up with a way to use post-install hooks to get this working. I'll PR this here shortly and then we should be good to go.
