Subject: Add new config module to set keyboard layout (#1176)

Adds a new module to allow setting keyboard layout,
for use-cases in which cloud-init is used to configure
OS images meant for physical computers instead
of the cloud.

This initial release only implements support
for Linux distributions that allow layout to be
set through systemd's localectl.
