Update values.yaml (Fix synchronization of config db)

[wotsyula]

What this PR does / why we need it:

Have default config user match replication config user: https://github.com/jp-gouin/helm-openldap/blob/8efc199864ae5833edbe64fba701d3e3dddb474a/templates/_helpers.tpl#L78-L83

This allows config database to also be synced between masters.

This is a quick fix. A more permanent solution would be to add Values.env.LDAP_CONFIG_ADMIN_USERNAME to binddn below: https://github.com/jp-gouin/helm-openldap/blob/8efc199864ae5833edbe64fba701d3e3dddb474a/templates/_helpers.tpl#L78-L83
