CLI refresh

[egorgripasov]

• rename cli-data -> cli-party
• Merge cli-party vs cli-echo
• Device invitation goes to cli just like halo
• update common logging (e.g., table vs json)
• query echo items (as table now, print graph eventually)
• query DXNS records (with similar query DSL to echo)
• move signal into cli-mesh
• move services into cli-kube
