kw ssh must handle the first ssh connection

[rodrigosiqueira]

Description:

The IP might change when we have a test machine connected to a very simple local network. However, even if you update kworkflow.config file to reflect the new change, you will see this message:

We could not reach the remote machine by using:
 IP: IP
 User: root
 Port: 22
Please ensure that the above info is correct.
Suggestion: Check if your remote machine permits root login via ssh
or check if your public key is in the remote machine.

Next, if you try to manually ssh to the machine, you will notice that kw failed because of this:

The authenticity of host 'IP (IP)' can't be established.
ED25519 key fingerprint is SHA256:DDDD.
This host key is known by the following other names/addresses:
    ~/.ssh/known_hosts:5: IP
Are you sure you want to continue connecting (yes/no/[fingerprint])?

You just have to say yes, and everything will work fine. This is super annoying and can mislead users; we need to improve how we handle ssh connections inside kw.

We probably need something simple like:

ssh -o "StrictHostKeyChecking no" user@host

Type:

Others

Why:

• We don't want to mislead users
