[keycloak-user] Admin Client for Java

[Vagelis Savvas]

Hello,

I am using the Admin Client Java library to administer Keycloak 
resources (users,roles, groups, etc.)
for a multi-tenant REST API running on Wildfly.
I wonder what's the recommended usage of the library in this context, 
where multiple concurrent requests are the norm.
Is it multi-threading safe? Should I use one instance for all tenants or 
maybe an instance per tenant?
Cheers,
Vagelis
