The current default causes spurious pulls even when the image is already
locally available, at least with podman 2.0.x. Looking through podman
how-tos, none mentions that this prefix is required, and the
image_default_transport in containers.con is generally "docker://". So
it's safe to drop it for better default behavior.
If a custom local setup deviate, users can still override
KAS_CONTAINER_IMAGE_PATH, prepending what is desired.

This patch introduces new and improved ways to overwrite kas-container
variables that specify which image should be used.
`KAS_CONTAINER_IMAGE_PREFIX`: can be used to overwrite image sources.
For instance if podman is used, the default value `docker://` is used as
a prefix. But it still allows to overwrite it, by setting a custom
variable.
`KAS_CONTAINER_IMAGE_PATH`: can be used to customize the image source
path.
`KAS_CONTAINER_IMAGE_NAME`: can be set to change the container image
name. For instance if `--isar` is used, the default value is
`kas-isar`, as with `KAS_CONTAINER_IMAGE_PREFIX` this default value can
still be overwritten by setting a custom value.
And last `KAS_IMAGE_VERSION`: It was possible to overwrite this value
before this patch and its still possible. The default value is the
current release version. Setting it for instance to `latest`, would
allow to used the most recent version of the image.

Some variables used by the `kas-container` script have rather generic
terms, that might be used in bitbake recipes. This change prefixes all
variables with `KAS_` to avoid those possible variable name conflicts.
