Write a new connection plugin for parallel-ssh.

Unless you or someone else write a connection plugin I guess not, since
I highly doubt Ansible/RedHat would write one.


Before writing a connection plugin you should look into forks,
pipelining, free strategy and async to get better performance in
Ansible.

Isn't this equivalent to the SSH controlmaster feature on openssh?

I mean eventhough ansible controller has forking and pipelineing concept with native ssh - seems to native ssh connection establishment will block IO operation that is reason parallel-ssh is good option and save time if controller wants to connect thousands of hosts Ref: https://github.com/ParallelSSH/parallel-ssh#ansible
