Enable Lint Rule: exported (jaegertracing#5525)

## Which problem is this PR solving?
-  Partial Fix for jaegertracing#5506

## Description of the changes
- Enabled exported in revive linter
- Converted struct `Config` to `ConfigurationV2`
- Converted struct `DependencyStoreParams` to `Params`
- Converted struct `SamplingStoreParams` to `Params`

## How was this change tested?
- `make lint` `make test`

## Checklist
- [x] I have read
https://github.com/jaegertracing/jaeger/blob/master/CONTRIBUTING_GUIDELINES.md
- [x] I have signed all commits
- [ ] I have added unit tests for the new functionality
- [x] I have run lint and test steps successfully
  - for `jaeger`: `make lint test`
  - for `jaeger-ui`: `yarn lint` and `yarn test`
