Add namespace and role resources for user settings

[jerolimov]

Fixes:
https://issues.redhat.com/browse/ODC-4755

Analysis / Root cause:
Based on the User Settings for OpenShift Console enhancement proposal we want to create a ConfigMap for each individual user in the namespace openshift-console-user-settings

We create a ConfigMap with a service account from the console bridge, see PR openshift/console#7095. For this we need that the namespace, role and rolebinding which is added in this PR.

Solution Description:

• Add Namespace openshift-console-user-settings
• Add Role and RoleBinding console-user-settings-role-operator to allow the ServiceAccount to get, list, create, update and delete Role, RoleBinding and ConfigMap in this new namespace.

@spadgett Can you take a look or assign this issue to someone who can review this change and openshift/console#7095?

Lets drop the -operator suffix. It's a bit confusing since there is actually no operator that would be handling the openshift-console-user-settings namespace.
Also most of the time we are not adding the -role suffix as well since the resource is Role itself.
In case we want a name that would reflect the role, I would rather go with console-user-settings-admin

Rebased and added a new label:

console.openshift.io/user-settings: "true"

@jerolimov noticed you added the console.openshift.io/user-setting label to all the resources. Havent found that label documented anywhere, can you please provide any info about it ?

@jhadvig You're right 👍 , based on this discussion in slack I removed the labels again.
