JSCH - Java Secure Channel - issue with sha2 known_hosts entries 

A video of what is being fixed

According to https://groups.google.com/forum/#!topic/repo-discuss/9PTfVG8vdAU for https://github.com/eclipse/jgit/blob/master/org.eclipse.jgit/src/org/eclipse/jgit/transport/JschConfigSessionFactory.java#L191

the known_hosts file encoding is the issue - needs to be ssh-rsa not ecdsa-sha2-nistp256 which jgit is unhappy with.

ubuntu@ip-172-31-15-176:~$ cat ~/.ssh/known_hosts 
|1|RFSqL1D1fCROw=|fcc8BqvMOekw0RLOz7Ts= ecdsa-sha2-nistp256 AAAAE...akI=

fix
ubuntu@ip-172-31-15-176:~$ ssh -v ubuntu@gerrit2.ons.zone 2>&1 | grep ~/.ssh/known_hosts 

debug1: Found key in /home/ubuntu/.ssh/known_hosts:2
ubuntu@ip-172-31-15-176:~$ sudo vi ~/.ssh/config
Host gerrit2.ons.zone

mysqldb  Opaque  2     0s
NOTES:
MySQL can be accessed via port 3306 on the following DNS name from within your cluster:
mysqldb.default.svc.cluster.local
To get your root password run:
    MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace default mysqldb -o jsonpath="{.data.mysql-root-password}" | base64 --decode; echo)
To connect to your database:
1. Run an Ubuntu pod that you can use as a client:
    kubectl run -i --tty ubuntu --image=ubuntu:16.04 --restart=Never -- bash -il
2. Install the mysql client:
    $ apt-get update && apt-get install mysql-client -y
3. Connect using the mysql cli, then provide your password:
    $ mysql -h mysqldb -p
To connect to your database directly from outside the K8s cluster:
    MYSQL_HOST=127.0.0.1
    MYSQL_PORT=3306
    # Execute the following command to route the connection:
    kubectl port-forward svc/mysqldb 3306
    mysql -h ${MYSQL_HOST} -P${MYSQL_PORT} -u root -p${MYSQL_ROOT_PASSWORD}
