Save bearer token in session_storage

[enriquezrene]

After a user log-in into the application, Azure AD returns a token that needs to be used for further interactions with the backend. We need to store this token in the browser session storage so it can be used for that and also let's save the tenant_id which comes in the token.

Acceptance Criteria

• Check if the bearer_token contains the tenant-id (Azure B2C id), if not make the required work to have it.
• Save the tenant_id as part of the session storage with the key_name tenant_id
• Save the bearer token in the session storage with the key_name bearer_token
