generic way to specify the endpoint to poll

Registered by Lianhao Lu on 2013-11-15

By adding a new optional item 'resources' in the pipeline definition, it will allows the admin to specify which endpoints the pollsters defined in the same pipeline to get the data from.

The new pipeline definition would be something like the followings:

-
name: meter_pipeline
interval: 600
meters:
        - "*"
resources:
        - snmp://10.4.4.4
        - ipmi://10.5.5.5
transformers:
publishers:
       - rpc://

How to intepret the content of the 'resources' field will depends on pollster.

    Add resource loader support

[Updated 01/24/2014]
According to the discussion in the IRC meeting, http://eavesdrop.openstack.org/meetings/ceilometer/2014/ceilometer.2014-01-23-15.03.log.html, it is agreed that we could leave the 'resource loader' functionality to individual pollster, instead of having a separate resource loader module. So I will abandon the resource loader patch and mark this bp completed.
