Enforce log hints in ofagent and oneconvergence

This change enforces log hints use and removes debug level log
translation, modifications are validated through a hacking rule
and the change respects loggging guidelines. Validate that hacking
rules apply to directories:-
    neutron/plugins/ofagent
    neutron/plugins/oneconvergence

Print version info at start

When debugging problems from logs, it would be useful to know what
version is running across program start and stop.  In one case I have
a suspicion that an upgrade was run inbetween but the logs don't help
identify that.

My first thought was to grab this from argparse just as --version
does, but that's not really currently possible [1].

The original starting message is probably irrelevant, but I realise
log messages tend to suffer from Hotel California syndrome; you can
check-in but you can never leave.

Split services code out of Neutron, pass 1

- After l3_agent is refactored, need to remove services/firewall
- After vmware plugin moves services out of monolothic,
  remove model copies and services/loadbalancer/constants,
  and re-enable unit tests.
- After alembic chain gets split in four, tweak models/head and
  fix heal/current chain.
- Re-factor test_routerserviceinsertion into one of the service repos

Remove TODO for H404

There is no timeline or intention to fix this - it's a non-functional
formatting change.
