target/ssh.py: add HostKeyAlgorithms option to test commands
After recent updates to the autobuilder tumbleweed workers there are tests where the client and
server fail to agree on a public key algorithm for host authentication:
DEBUG: [Running]$ ssh -l root -o PubkeyAcceptedKeyTypes=+ssh-rsa -o UserKnownHostsFile=/dev/null
-o StrictHostKeyChecking=no -o LogLevel=VERBOSE 192.168.7.6 export PATH=/usr/sbin:/sbin:/usr/bin:/bin; uname -a
DEBUG: time:
1634578090.
4632802, endtime:
1634578390.
4592378
DEBUG: Partial data from SSH call: Unable to negotiate with 192.168.7.6 port 22: no matching host key type found. Their offer: ssh-rsa
This appears to be an issue with recent versions of shh. Add -o HostKeyAlgorithms=+ssh-rsa to
command invocation as suggested at:
