Created readonly perses server from samples

[vinodhreddyg]

Below are the steps

• Deploy perses operator
• Perses server is created from the CR available at https://github.com/perses/perses-operator/blob/main/config/samples/perses.dev_v1alpha1_perses.yaml
• Apply dashboard CR at https://github.com/perses/perses-operator/blob/main/config/samples/perses.dev_v1alpha1_persesdashboard.yaml

This perses server is readonly I'm not able to perform any operations.

Error logs:
