Subject: Adding Future method for DialerPhoneNumberUtil

This CL adds a method to DialerPhoneNumberUtil which returns a Future
holding the result of parsing a number into the DialerPhoneNumber proto.

This will be used in the APDL integration as it will use Futures as
well.

The CL also changes DialerExecutors.lowPriorityThreadPool to be an
ExecutorService instead of an Executor (the super type) so it can be
used in MoreExecutors.listeningDecorator.
