Use the officially supported apache mina sshd in m2k-func

The various git command we use in m2k func now uses the officially
supported ssh implementation for the transport.

Added tests to see the transport is working well with ed25519 keys

Notice - the StrictHost option is now set using a standard ssh_config
(see man ssh_config) file which is assumed to be where the key is located -
so now we can just drop the id_rsa file in a well known location along
with the rest of the .ssh files:

/etc/.ssh/config
/etc/.ssh/known_hosts
/etc/.ssh/id_rsa
