Daniel Kimsey 4243e1e05f Add support for filtering the 'List Services' API
1. Create a bexpr filter for performing the filtering
2. Change the state store functions to return the raw (not aggregated)
   list of ServiceNodes.
3. Move the aggregate service tags by name logic out of the state store
   functions into a new function called from the RPC endpoint
4. Perform the filtering in the endpoint before aggregation.
