new activation servicesdev-dct-activation-switch-2

During startup, new services lvm-activate-vgs-main and
lvm-activate-vgs-last run fixed point in time
vgchange -aay commands to activate all VGs.

The vgchange in the -last service includes the option
"--eventactivation begin" which creates the
/run/lvm/event-activation-on file, which enables
event-based activation from pvscan commands.

The lvm-monitor service starts after lvm-activatae-vgs-last.
