Lucas Alvares Gomes 25d3ee5471 Add dynamic-login element
Troubleshooting an image can be quite hard, specially if you can not get
a prompt you can enter commands to find out what went wrong. By default,
the images (specially ramdisks) doesn't have any SSH key or password for
any user. Of course one could use the ``devuser`` element to generate
an image with SSH keys and user/password in the image but that would be
a massive security hole and very it's discouraged to run in production
with a ramdisk like that.

This commit is adding a new element called dynamic-login, which inserts
a helper script into the image to allow operators to inject a SSH key
and/or change the root password dynamically when it boots via parameters
in the kernel command line.

Those parameters are:

sshkey = If the operator append sshkey="$PUBLIC_SSH_KEY" to the kernel
command line on boot, the helper script will append this key to the root
user authorized_keys.

rootpwd = If the operator append rootpwd="$ENCRYPTED_PASSWORD" to the
kernel command line on boot, the helper script will set the root password
to the one specified by this option. Note that this password should be
an encrypted password.
