Add REST implementation for Validator's ValidatorIndex (#11712)

Browse Source 
* Add GetAttestationData

* Add tests

* Add many more tests and refactor

* Fix logic

* Address PR comments

* Address PR comments

* Add jsonRestHandler and decouple http logic from rest of the code

* Add buildURL tests

* Remove handlers_test.go

* Improve tests

* Implement `ValidatorIndex` of `beaconApiValidatorClient` using Beacon API

* Implement getStateValidators

* `validatorIndex`: Use `getStateValidators`
