[FEATURE] Basic auth support for Redfish

[starbops]

Is your feature request related to a problem? Please describe.

Currently, KubeVirtBMC only supports token-based authentication for the Redfish service. It'd be nice to have the basic auth also supported so that users can interact with the service using commands like curl -u <username>:<password> ....

Describe the solution you'd like

Support HTTP Basic Auth for Redfish.

Describe alternatives you've considered

N/A

Additional context

This is one of the remaining items from #2.

Hi @anishbista60 For basic auth, please refer to the Authentication chapter in the official doc https://www.dmtf.org/sites/default/files/standards/documents/DSP2060_1.1.0.pdf.

When using HTTP Basic authentication, users will need to provide this header in each request to the service. This
means that the service will need to verify the username and password on every request.
