`known_hosts` management

Description

We can add action to manage known_hosts on servers.

Proposal

API:

• ssh_known_hosts:
  • host
  • key

Questions:

• there is no easy way (I mean it is not supported by ansible module) to synchronize full known_hosts file. I am not sure if I even care... so do we care about removing hosts from known_hosts or we will just add hosts to this file?
