Re: Add serverlist resolver

Settings and srv resolvers are contained in PUP-10037, as they are needed to connect to the CA. So this ticket is just to add the server_list resolver.

Add serverlist resolver

Change By:	Josh Cooper

Each resolver should resolve the host and port for a service based on its name and offer multiple candidates.

* The settings resolve should use the corresponding Puppet settings. For example, the CA service should resolve to {{Puppet[ : ca_server]}} and {{Puppet[ : ca_port]}}, which default to the {{Puppet[ HTTP : server]}} and {{Puppet[ : masterport]}}. Resolver::ServerList should implement the Resolver interface
* The server_list resolver should use {{ Puppet Puppett [:server_list ] }} to yield servers
* The SRV resolver should use Should try to make GET request to the service name simple status endpoint to see if the server is available
* Only if the HTTP request is 200 do we use that server
* Default port to {{masterport}} if port is omitted from server_list
* Rescue exceptions, log debug message, and SRV domain continue next server
