Turn hook_content_lock_release into an event

astonvictor → changed the visibility of the branch 3436549-turn-hookcontentlocklocked-and to hidden.

Created two new events (ContentLockLockedEvent & ContentLockReleaseEvent) and removed old hooks.
For new events, I used the same arguments as we had.

Left some comments on MR.

good point.
thanks
