Support --ipip option for calico pool

Browse source 
Adds new boolean configuration variable for calico network plugin
`ipip`. When it's enabled calico pool is created with '--ipip'
option (IP-over-IP encapsulation across hosts).

Also refactor pool creation tasks to simplify logic and make tasks
more readable.
