WHAT
3scale will soon deprecate highAvailability which dictates whether 3scale uses externally managed databases or not. externalComponents will replace this and changes will need to be made in the 3scale reconciler to support this change.

HOW
https://github.com/integr8ly/integreatly-operator/blob/700a983812bde380f1a1c0e1a52d28e20d3c0d1d/pkg/products/threescale/reconciler.go#L928 https://github.com/integr8ly/integreatly-operator/blob/700a983812bde380f1a1c0e1a52d28e20d3c0d1d/pkg/products/threescale/reconciler.go#L593

There will likely need to be changes made at both links above in the threescale reconciler.

go.mod needs to update the threescale operator from 0.7.0 to 0.9.0
