Update kepler version and container template

Update kepler image default version to v0.10.2.

The new kepler (starting from 0.10) has completely different set of
config options so kepler's template was updated correspondingly.

- Removed '-v' option as it's no longer supported.
- Added option --web.listen-address=:8888 as kepler no longer runs
  on port 8888 by default.
- There is no longer need to specify desired metrics using
  environment variables as all metrics are enabled by default.
