Feature: Adding google cloud storage support to DAS

[alberthuang24]

Is your feature request related to a problem? Please describe.
Currently we only support uploading das data to aws s3 or locally, we would like to support more cloud providers for storage so that we can decentralize the risk of centralized failures and reduce maintenance costs.

Describe the solution you'd like
Add google cloud storage(GcsStorageService)

Hi, when we wrote the DAS code we envisioned that entities that wanted to run a Data Availability Committee server or a mirror may want to write their own storage backends, so we made it so that there are just a few simple interfaces that need to be implemented

nitro/das/das.go

Line 23 in 09d45c1

type DataAvailabilityServiceWriter interface {

nitro/das/das.go

Line 29 in 09d45c1

type DataAvailabilityServiceReader interface {

nitro/das/das.go

Line 34 in 09d45c1

type DataAvailabilityServiceHealthChecker interface {

This is something we'd be happy to accept third-party contributions for. Otherwise we will get to this when we can, but it's not currently prioritized.

Support was added in #2643. GCS is not supported by OCL, so it is not guaranteed to work.
