Updated SSH Documentation

Add your public key to $TIS-DEVOPS/ansible/roles/ssh/files/public_keys/:email. , keys should be in OpenSSH format.
The following command needs to run to give access to the build server

`$ ansible-playbook -i inventory/build tasks/ssh.yml`

3. It may be useful to add the following to your ~/.ssh/config file (you can create a new text file in that location if you don't already have one).

We swapped platforms recently so some of the keys for the servers no longer match the original values. If you see a message similar to this when you try and connect then you will need to remove entries from your known hosts;

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:O6QtBrIMNz0c/OKPGmRLhEsQwOm4eeFgcPkd/yClwcs.
Please contact your system administrator.
Add correct host key in ~/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in ~/.ssh/known_hosts:1061

You have two options;

Delete your ~/.ssh/known_hosts file to remove all stored public keys.
Find the entries in ~/.ssh/known_hosts that are conflicting. In the case of the example above, the key on line 1061 was causing the problme so removing that line fixed the issue.
