[PATCH] isar-installer: Added option to add additional kernel cmdline arguments for isar-image-installer.

[PATCH] isar-installer: Added option to add additional kernel cmdline arguments for isar-image-installer.

[alexander.heinisch via isar-users]

From: Alexander Heinisch <alexander.heinisch@siemens.com>

In combination with unattended mode this allows to specify
several settings like target device, target image path, aso.
to be specified during buildtime.

As this is specific for the installer image:

Should we prefix the variable with INSTALLER_ (or something similar?)

While having such a prefix makes it more clear to the user, 
most of the user's setup installer image in a multiconfig env.
Thus, there shouldn't be too much conflict/confusion.

On the other hand, once we have unique `ADDITIONAL_KERNEL_CMDLINE`
it allows for easier swapping of wks files once adoption of 
`--append="...${ADDITIONAL_KERNEL_CMDLINE}"` is available for multiple wks files.

e.g. a signed installer image, could reuse parts of a generic wks for signed ukis
only adding the additional `/install`.

Maybe that's YAGNI, so I am completely open to adding the prefix as well, 
those were just the thoughts/concerns I had in mind when coming up with the unified approach.

Hello Alexander,

Can you also add any kind of usage example?

You can find some examples here: https://github.com/ilbers/isar/commit/4c66faf1110ded164440df8108effef7e9a52d34
 
 - installer.unattended
 - installer.image.uri ...file name of the image to be installed (parameter name uri chosen since we plan to support download of images in upcoming patches)
 - installer.target.dev ...target device name (e.g. /dev/sda) for the image to be installed to
 - installer.target.overwrite ...strategy how to handle target devices not empty (possible values: OVERWRITE - overwrite data on target | ABORT - abort installation if target not empty)

I will put the link and a short description in the commit message!
Since, I plan to push further changes for the target bootstrapping, 
I'd prefer to update the documentation, once that's done.

Thanks, but I mean the usage of ADDITIONAL_KERNEL_CMDLINE with any
sample target, so we will have all the way of that variables starting
from image generation to have them handled in handle-config.sh.
This will help to keep tracking this functionality for regressions.
