Separate Display Name From username_attribute

[jvincze84]

Hi All,

The user name displayed in the top right corner should be separated from the username_attribute setting in opensearch-security/config.yaml, because it is also used for user role mapping.

In our case we would like to use displayName LDAP attribute to show in the OpenSearch dashboard top right corner.
But the displayName is not a uniq attribute in LDAP, it can cause problem in user's role mapping.

Thanks,
Janos Vincze
