These don't necessarily need to be done in the image itself but you
can virt customize the image prior to uploading it to the undercloud
to inject some things. We provide ways of configuring these things at
deployment time.

We have sshd configured via a service. Available options are listed in
the service file:

This can be done via a firstboot script.

You'd probably want to do this via a first boot as well. If you are
deploying with overcloud images, technically you shouldn't need a
proxy on install but you'd likely need one for subsequent updates.

See KernelArgs.

Your best reference for what is available is likely going to be by
looking in the THT/deployment folder for the service configurations.
We don't expose everything but we do allow configurability for a
significant amount of options.  *ExtraConfig can be used to tweak
additional options that we don't necessarily expose directly if you
know what options need to be set via the appropriate puppet modules.
If there are services we don't actually configure, you can define your
own custom tripleo service templates and add them to the roles to do
whatever you want.
