Add logic for using Auth.Period when handling auth login/renew requests (#3677) 

* Add logic for using Auth.Period when handling auth login/renew requests

* Set auth.TTL if not set in handleLoginRequest

* Always set auth.TTL = te.TTL on handleLoginRequest, check TTL and period against sys values on RenewToken

* Get sysView from le.Path, revert tests

* Add back auth.Policies

* Fix TokenStore tests, add resp warning when capping values

* Use switch for ttl/period check on RenewToken

* Move comments around
