Integrate keycloak auth with frontend

[VigneshVSV]

The purpose is implement a basic redirection and an authentication GUI

Rough steps:

• Add an account symbol either on top right or top left or in a meaningful place
• Integrate react-oidc-context package and its authentication context into the app
• On click of the login, redirect to keycloak. A test user will be available, make sure authentication proceeds and redirect back to the frontend
• create OIDC secrets in the CI that will be deployed along with the frontend docker container
• Place a GUI within keycloak (built HTML) or a local GUI where the login page looks similar to our styles. I think the convention is to place it in keycloak, because, otherwise the redirection dont make sense.
