option_parser: Create generic type Tuple

Browse Source 
Creates a new generic type Tuple so that the same implementation of
FromStr trait can be reused for both parsing a list of two integers and
parsing a list of one integer associated with a list of integers.

This anticipates the need for retrieving sublists, which will be needed
when trying to describe the host CPU affinity for every vCPU.
