Getting error in operator while following docs/deploy-operator.md

[onprem]

I was trying to deploy Observatorium in a local cluster. I followed the instructions in docs/deploy-operator.md, everything worked fine until the "Deploy an example CR" step.

After deploying the CR, nothing was showing up in the observatorium namespace, so I checked the operator logs and found this:

Some observations

• The error RUNTIME ERROR: Field does not exist: table_manager seems to be related to Loki configuration.
• I tried removing the Loki part from example/manifests/observatorium.yaml. Deploying it worked, this further solidifies the speculation that the Loki part is causing some problems.
• I also tried running ./tests/e2e.sh kind and then ./tests/e2e.sh deploy-operator and it worked.
