Questions: * The implementation is now KeyCloak specific in part of using realms as a substition for Keystone projects (multitenancy). Based on a realm name (in fact, project name) we build a url where we send auth requests. Can we move away from KeyCloak specifics and provide a pure OpenID Connect implementation? TODO: * Reusing existing token * Refreshin a token NOTE: This addition now looks slightly hacky because we try to put all possible auth parameters into Client initializer. Ideally, authentication method should be pluggable similar to the new Keystone approach with separation sessions and authentication methods (see keystoneauth project). This separation can be addressed only in Mistral future versions because all changes in API/CLI v2 have to be backwards compatible. API/CLI v3 must address this architectural issue.
