Fixes #38498 - Add Reboot power operation to Redfish provider

Bug #3073 is caused by 3 things:
1. Foreman core doesn't call BMC proxy's API correctly
   - Changing power state to 'Reboot' via Web GUI calls BMC proxy's 'soft'
     power action
   - Changing power state to 'Reset' via Web GUI calls BMC proxy's 'cycle'
     power action
2. Foreman BMC proxy doesn't support reboot at all BMC provider
3. Foreman BMC proxy doesn't support reset(powerreset) at Redfish provider

2nd & 3rd item are mentioned in #38498. And this PR fixes 2nd item.

For backward compatibility, power_action_v2 capability is introduced
to smart proxy at PRs related to #38498. PR related to #3073 adds logic
to determine if smart proxy supports this capability into Foreman core.
