shill: DHCPConfig: Get new lease with RenewIP

If a DHCP process is not running when RenewIP is called, acquire
a new lease instead of returning.  This allows callers external
to shill to avoid having to keep track of whether the IPConfig
object has a lease or not.

BUG=chromium:318290
TEST=Unit test + manual: Reproduce the issue in crbug.com/318290.
In specific, change the IP address to a static IP first and close
the configuration panel, then separately switch to custom name
servers.
