[RFE] Add --timeout argument

[grafuls]

Is your feature request related to a problem? Please describe.
Sometimes we might want to do a racreset and check back on the status of the redfish api to see when the idrac is back up by checking for example the power status via --power-state. This command might sometimes take too long to timeout but we could give it less time given that we already know that system is restarting. Would be nice to be able to state the timeout so as to reduce the waiting time.

What System / IPMI Platform?
IDRAC 9

Describe the Possible Solution
Add an optional argument --timeout that takes integer values and appends this to each REST call.
