[RFE] Replace BasicAuth with Session-based authentication (JWT)

[grafuls]

Is your feature request related to a problem? Please describe.
Token based authentication is going to reduce the number of times we must send credential to the server. Servers that use tokens can improve their performances, because they do not need to continuously look through all the session details to authorize the user’s requests.

What System / IPMI Platform?
ALL

Describe the Possible Solution
Create an X auth session via POST with payload {"UserName":$U,"Password":$P} to /redfish/v1/SessionService/. Retrieve the token from the response and store in memory then pass it on every subsequent request through the header like {'X-Auth-Token': $TOKEN}.
Close the session via DELETE to /redfish/v1/SessionService/Sessions/$SESSION_ID.
