Provide credentials in new hosts

[jmolmo]

In order to execute playbooks in new hosts we require first to have password-less access to these new hosts.
In this moment we are doing this in a manual way, copying the Ansible Runner Service root user ssh public key to the new hosts.

Probably the procedure basically is to execute:
ssh-copy-id -i ~/.ssh/mykey.pub user@host

we will need to provide "user" password in "host" to complete the operation, but once the operation has been executed we will have the kind of access required.
