kernel: allow to override modules & sysctl settings
Allow to easily personalize Kernel modules and sysctl settings with two new parameters. ExtraKernelModules and ExtraSysctlSettings are dictionaries that will take precedence over the defaults settings provided in the composable service. Closes-Bug: #1742440 Change-Id: I9cd43331e5e9a6074cd47040c29815ca32c61693
