Pull request description:
## Type of Change
<!-- Put an `x` in the boxes that apply -->

- [ ] Bugfix
- [ ] New feature
- [ ] Enhancement
- [x] Refactoring
- [ ] Dependency updates
- [ ] Documentation
- [ ] CI/CD

## Description
<!-- Describe your changes in detail -->
This PR adds the info logs to log the dynamic routing grpc requests and response objects.

### Additional Changes

- [ ] This PR modifies the API contract
- [ ] This PR modifies the database schema
- [ ] This PR modifies application configuration/environment variables

<!--
Provide links to the files with corresponding changes.

Following are the paths where you can find config files:
1. `config`
2. `crates/router/src/configs`
3. `loadtest/config`
-->


## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
-->


## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
-->

1. Create merchant_account, api_key and mca (any connector)
2. Toggle dynamic routing

```
curl --location --request POST 'http://localhost:8080/account/merchant_1734609410/business_profile/pro_gPTjn9jLm0CxI8ZD1omL/dynamic_routing/success_based/toggle?enable=metrics' \

--header 'api-key: dev_K70Wr6zqJLbPECg8eEXrnZ43TW41JNUuXYHzRB50geiG0lViLExjxNUld6sgdNd0' \
--data ''
```

3. Set 100% for dynamic_routing volume split

```
curl --location --request POST 'http://localhost:8080/account/merchant_1734609410/business_profile/pro_gPTjn9jLm0CxI8ZD1omL/dynamic_routing/set_volume_split?split=100' \
--header 'api-key: dev_GFInyC2oIihPleQ4CM8u8WOa02PxN5MHR5W1YAZyXxIYTHt8KDq2VPzRNn26JyJI'
```

4. Create a payment

```
