ipmi/command.py: Add bridge_request argument to set|get_power

Browse Source 
Add bridge_request argument to set_power and get_power so that the
power request can be sent to the remote target.

For example of the usage:
    ipmi_cmd = command.Command(bmc, userid, password)
    ipmi_cmd.get_power(bridge_request={"addr": 0x20})
