Sergii Golovatiuk 45044c2d75 Reschedule netchecker-server in case of HW failure.
Pod opbject is not reschedulable by kubernetes. It means that if node
with netchecker-server goes down, netchecker-server won't be scheduled
somewhere. This commit changes the type of netchecker-server to
Deployment, so netchecker-server will be scheduled on other nodes in
case of failures.
