Abstract Resources (#256)

* intro scheduler v2: adapter to v1

* cluster: rewrite create and realloc

* types: introduce resource interface to unify

* scheduler: expose SelectNodes to encap ScheduleV1

* store: new UpdateNodes and Processing interfaces

* strategy: adjust to new resource data structure

* rpc: create option harness resource interface

* utils: minor fix to transaction

* pass lint and codacy

* fix transactions for realloc and replace
