KMM Day1 should support multiple modules

[yevgeny-shnaidman]

Currently KMM Day functionality supports replacing only one kernel module during linux kernel initialization.
We should allow support for replacing multiple modules during kernel initialization.
There are 2 possible implementation option:

1. All the module are stored in the same image. The systemd service will be changed to go over a list of modules and replace each on of them. This will require changing the package API implementation to receive a list of modules
2. Each such kernel module should be replaced using a different MachineConfig. This will require making sure that the systemd for each such MC are not named and located at the same place, in order not to override one another

The first option seems more feasible, since it won't require user to create multiple images, and will require only one call to the package API
