Display output for minions that did not return

This outputter is used to display notices about which minions failed to return when a salt function is run with -v or --verbose. It should not be called directly from the CLI.

Example output:

virtucentos:
    Minion did not return

class salt.output.no_return.NestDisplay

Create generator for nested output

display(ret, indent, prefix, out)

Recursively iterate down through data structures to determine output

salt.output.no_return.output(ret, **kwargs)

Display ret data
