> Token init command authenticates clients and then requests identity token.
> The result token is then persisted in token cache for later usage, being
> available for cross components, to support single sign on. The scope of this
> is as follows:
>
> * Define token storage handler;
> * Define token cache API for storing, accessing, removing of token;
> * Define token cache file location, configuration and etc.
> * Implement default token storage handler based on local file located in user
> home directory.
