Add --ssh option to command-line commands
Enables using the new ssh client based on Apache MINA sshd instead of the old JSch client. The default is still JSch, so unless the command is invoked with --ssh apache, there's no change. I prefer this over some fiddling with the GIT_SSH environment variable since that variable is handled in the JGit core bundle, which should remain free of any dependency to org.eclipse.jgit.ssh.apache to avoid problems in Gerrit or other JGit users that may use a different Apache MINA sshd version. Bug: 520927 Change-Id: I8460759c7113ef7887520fb0d297aa312200c69f Signed-off-by: Thomas Wolf <thomas.wolf@paranor.ch>
