Reconcile peer configs to a secret

[paddyoneill]

Relates to #211

Remove the peer config from status, and reconcile to a secret. This implementation creates a secret per wireguard, and adds peer configs as keys. This allows peer configs to be retrieved using kubectl get secret/<wireguard-name>-peer-configs -o jsonpath='{.data.<peer>}'

For example

kubectl get secret/test-vpn-peer-configs -o jsonpath='{.data.my-peer}' | base64 -d

Hi @paddyoneill, appologies for the slow response. Are you still interested in getting this merged?

I'd like to merge #185 first and then I'll fix any conflicts with your branch and merge it :)

#185 is really important as the code is currently a big mess and we need a structure..
