Support query filtering for templates and EDP objects

Allow query params to be passed through the REST API for the
following objects:

* cluster templates
* node group templates
* data sources
* jobs
* job executions
* job binaries
* job binary internals

Suppress an exception when invalid filter fields are used,
simply return empty list.

Support query filtering for cluster objects

The cluster_get_all implementation already supports query
parameters internally, but it is not exposed to the UI. Allow
query params to be passed in from the UI. Suppress an exception
when invalid filter fields are used, simply return empty list.
This will be a model for adding filtering to all x_list() methods
in the API.
