Create new grpc storage configuration to align with OTEL (#5331)

## Which problem is this PR solving?
- part of #5229 

## Description of the changes
- added more grpc storage client configuration to align with otel
 ```
	configgrpc.ClientConfig        `mapstructure:",squash"`
	exporterhelper.TimeoutSettings `mapstructure:",squash"`
 ```
These are not all the configs, but i'll add more based on feedback on
this initial approach.

## How was this change tested?
- not tested yet 

## Checklist
- [x] I have read
https://github.com/jaegertracing/jaeger/blob/master/CONTRIBUTING_GUIDELINES.md
- [x] I have signed all commits
- [x] 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`
