Assume all nodes matching the search query are valid nodes #272

Previously we checked if nodes were matching search query AND had an existing chef key.
This patch assumes that all nodes have exiting chef keys.

Experience I have with chef is that nodes without proper keys are bugs and needs
to be fixed anyway (either have a key or be removed).

This patch allows to make usage of --clean-unknown-clients much faster (avoid
querying chef-server for each node) especially on secrets encrypted for many
nodes (where search query time is small compared to querying all clients)

I'm of course willing to discuss the assumption "all nodes have a client" (got no answer on slack https://chefcommunity.slack.com/archives/C0M1NGZE3/p1493210220884148).

Yeah, I don't really understand why you'd get to a position of having nodes without clients, unless you have a terrible reaper program that only deletes clients.

This introduces a small change in behavior:
- before: existing nodes without client would be cleanup by --clean-unknown-clients
- now: such nodes are not cleaned. They will be cleaned when node will be removed
