Operator: main build fails to reconcile secrets

[rfratto]

@stevo-f3 reported in #1271 that the operator is failing to reconcile on secrets:

level=info ts=2022-02-01T18:57:31.693552638Z component=controller.grafanaagent msg="Starting workers" workercount=1
level=info ts=2022-02-01T18:57:31.693623302Z component=controller.grafanaagent name=foo namespace=bar msg="reconciling grafana-agent"
level=error ts=2022-02-01T18:57:31.694405371Z component=controller.grafanaagent name=foo namespace=bar msg="unable to build hierarchy" err="failed to discover secrets: failed to find \"/v1, Kind=SecretList\" resource: list failed: Index with name field:metadata.name does not exist"

This is likely caused by the ongoing refactoring to help test and maintain the code more easily.

Maybe this applies kubernetes-sigs/kubebuilder#547 (comment)

Thanks @stevo-f3, that was definitely helpful! And thanks for reporting too, sorry we had missed this initially.
