I'm not sure of whether or not these things work in the status of these
things in fedora/RHEL. I suspect that all below is true other than
disk space resize. However, the following is true for ubuntu:

- hostname is set to whatever is in local-hostname of the metadata
service. I think that actually does correlate to 'name' in the nova
launch api.

- cloud-init runs resize2fs on the root partition on start up. However,
if you have a partition table on the disk, right now, that relies upon
initramfs code delivered in cloud-initramfs-growroot [1] to grow the
partition , and tell the kernel to re-read the partition while the
filesystem is not mounted (otherwise you have to reboot).

> - ssh-key pull
- cloud-init does that by default to the default user and adds it to the
root user's .ssh/authorized_keys, with a message that says "you need to
login as <the-configured-user>"

- by default, cloud-init does not set a password for a user. However, it
can be told to via configuration (cloud-config in the image or passed
in via userdata). That looks like:
password: RANDOM
or
chpasswd:
list: |
user1:password1
user2:RANDOM
expire: True
There is more info at [2].
