[Neutron] Fix helm3 deployment by naming every migration-job specifically
[Neutron] Fix helm3 deployment by naming every migration-job specifically

   With Helm3, we don't force the replacements of job specs anymore, which
   causes deployment issues since kuberentes job specs are immutable by default.
   We solve this by generating an image specific name for every deployment,
   therefor no job will be replaced. Instead, a new job will be spawned while
   the old one will be deleted.
