feat: add receiver for redfish (open-telemetry#43279)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description
This PR is to add a redfish receiver. Redfish is an open standard API
that is commonly implemented on enterprise grade servers with BMCs
(baseboard management controller) used for both in-band and out-of-band
server management. This receiver provides a way for engineers to monitor
their servers and server components such as fans and temperature
sensors.

<!-- Issue number (e.g. #1234) or full URL to issue, if applicable. -->
#### Link to tracking issue open-telemetry#33724

<!--Describe what testing was performed and which tests were added.-->
#### Testing
Testing has been done on HPE iLO machines and logic similar to the
[Telegraf redfish input
receiver](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/redfish)
has been used (which I have contributed to in the past).
