Update LDAP Group Sync Templates for OCP 4.1

[darthlukan]

High level steps used on OCP 4.1 to set up LDAP group sync. Adding the steps here as requested via internal chat.

1. Create Secret named ldap-bind-secret in openshift-config namespace with data.bindPassword containing the base64 encoded bind password.
2. Create ConfigMap named ldap-ca-config-map in openshift-config namespace with data specced to ca.crt containing the CA Cert.
3. Create Namespace named infra-cronjobs with label name: infra-cronjobs
4. Create ConfigMap in the infra-cronjobs namespace containing data with ca.crt defined as well as ldap-group-sync.yaml containing the required data defined in the OCP 4.1 Auth Providers: AD/LDAP docs.
5. Create CronJob named ldap-group-sync in namespace infra-cronfjobs containing a spec consuming the items created prior.
6. Create ClusterRole named ldap-group-syncer with rules allowing get, list, create, update, and delete on group resources.
7. Create ClusterRoleBinding named system:ldap-group-syncers with roleRef set to ldap-group-syncer for ldap-group-syncer service account
8. Create ServiceAccount named ldap-group-syncer in namespace infra-cronjobs
9. Create Job named initial-ldap-group-sync in namespace infra-cronjobs which consumes the body of the CronJob created in step 5 in order to kick things off.

How do you map the synced user names to the base64 encoded user names when users are logging in?
