Add ClaimRootClientAuthToken and ConfirmRootClientAuthToken

Claim* call will create temporarily secret and set that as primary after
Confirm* is called.

Local client needs to be able to claim control of unclaimed device.
Device should be claimed no more than once, so if Claim was called and
client didn't not get response, we will have locked account. Confirm* is
used as that confirmation.
