Add some available resource types

1. What is the problem
Some resources are needed by asynchronous job, as described in [1],
'trunk_id' and 'portchain_id' are needed when create a job.
So we need to add these resources to allow resource routings
creation. Besides resources 'trunk_id' and 'portchain_id', other
resources are also needed in the tricircle, therefore all needed
resources are added at once by this patch. This problem also exists
in the tricircle, and it's fixed by patch [2].

2. What is the solution for the problem
Add some resource types to allow for resource routing creation.

3. What the features need to be implemented to the
tricircleclient to realize the solution
None.
