Fix RabbitMQ log output with Vault configured

[ansd]

This commit fixes the CI failure which tests the following example: https://github.com/rabbitmq/cluster-operator/tree/main/docs/examples/vault-default-user

RabbitMQ crashed at startup as follows:

failed to open log file at '/var/log/rabbitmq/rabbit@vault-default-user-server-0.vault-default-user-nodes.examples.log', reason: read-only file system

The problem was that with Vault configured the mount in

cluster-operator/internal/resource/statefulset.go

Line 876 in 575cfac

vaultAnnotations["vault.hashicorp.com/secret-volume-path-"+secretName] = "/etc/rabbitmq/conf.d"

seems to hide the config file in
https://github.com/docker-library/rabbitmq/blob/master/conf.d/10-defaults.conf containing the setting

log.console = true

Without any vault, the config directory in the RabbitMQ pod looks as follows:

k exec r1-server-0 -c rabbitmq -- ls /etc/rabbitmq/conf.d
10-defaults.conf
10-operatorDefaults.conf
11-default_user.conf
90-userDefinedConfiguration.conf

With vault configured, the config directory in the RabbitMQ pod looks as follows:

k exec vault-default-user-server-0 -c rabbitmq -- ls /etc/rabbitmq/conf.d
10-operatorDefaults.conf
11-default_user.conf
90-userDefinedConfiguration.conf

This commit fixes the issue by adding

log.console = true

to file 10-operatorDefaults.conf.

There is no harm if this setting is defined twice in different files in the /etc/rabbitmq/conf.d directory. The last one wins.
