Prevent too many ssh connections to one host #42

Closed babbageclunk closed 7 years ago

babbageclunk commented 7 years ago

In testing against an environment with many containers (~15 per host) we're seeing errors that look like we're trying to proxy too many SSH connections to containers via one host. Add a host throttler to parallelExec to limit the number of concurrent connections to a host.
