Sync period is way below the default value

[jnodorp-jaconi]

Describe the bug

The keycloak-realm-operator uses a sync period of five Minutes (see https://github.com/keycloak/keycloak-realm-operator/blob/main/cmd/manager/main.go#L108). This causes a massive load on the Kuberntes and Keycloak APIs, leading to throttling and an overall sloweness of the operator (when using many resources).

The default sync period is ten hours, and you should

Change this value only if you know what you are doing.

Version
