Redfish: Add options to check the availability of the service

[mraineri]

SUMMARY

• Adds new command to check if a Redfish service is available
• Adds new option to manager reset operations to wait for the service to become available again after the reset

Fix #8051

I did not add a changelog fragment yet; will do that once I get some eyes on the design.

ISSUE TYPE

Looks good to me, do you want to wait for more feedback or should I merge?

I'm good with merging it now; I asked other to review it on a call with me, so there were other eyes on the changes.
