**What type of PR is this?**
Other

**What does this PR do? Why is it needed?**
- Added log prefix to the `genesis` package.
- Added log prefix to the `params` package.
- `WithGenesisValidatorsRoot`: Use camelCase for log field param.
- Move `Origin checkpoint found in db` log from WARN to INFO, since it
is the expected behaviour.
